How Drone Inspections Improve Safety and Accuracy
Imagine being tasked with inspecting a high-rise building or an oil rig—places that are difficult to access, full of potential hazards. Traditionally, inspectors would have to scale heights, enter confined spaces, or work in hazardous environments to gather essential data. These conditions make inspections not only time-consuming but also risky. Industrial drone inspections are changing the game. By using drones to collect data remotely, industries can now complete inspections faster, more safely, and with higher precision. This revolutionary approach to LiDAR asset inspection and infrastructure inspection drones has increased operational efficiency and greatly reduced risk. In this blog, we’ll explore how drone inspections improve safety and accuracy, offering a glimpse into their growing role in industries such as construction, energy, and manufacturing. Plus, we’ll cover how inspection data reporting and risk reduction with drones are driving smarter decisions. The Power of Drones in Industrial Inspections Drone inspections have gained widespread adoption in the last decade, thanks to their ability to access hard-to-reach places quickly and safely. Whether inspecting a wind turbine, a building facade, or an oil pipeline, industrial drone inspections provide an efficient way to gather high-quality data. You hit your targets without putting inspectors in dangerous situations. When traditional inspections require workers to use scaffolding, ropes, or ladders, drones take over, flying to locations and capturing detailed imagery and videos. These drones can be equipped with high-definition cameras, thermal sensors, and LiDAR (Light Detection and Ranging) technology for even more precise data capture. Several studies confirm that drones greatly reduce inspection errors, help companies finish inspections on time and improve workplace safety by eliminating the dangerous terrain inspection people have to do. This incredible time-saving capability allows businesses to complete more inspections in a shorter amount of time, reducing costs and improving safety. Let’s dive deeper into how drone inspections work and how they enhance safety and accuracy in real-world scenarios. How Drones Enhance Safety in Industrial Inspections Safety is one of the most compelling reasons to use drones in industrial inspections. In industries like construction, oil and gas, and utilities, workers are often required to access high-risk areas such as confined spaces, high structures, or hazardous environments. With confined space inspections, workers previously had to enter cramped or dangerous areas, such as tanks or ducts, to assess conditions. This not only exposed them to potential harm but also slowed down the process. Drones change this by allowing inspectors to gather the necessary data without entering these spaces. For instance, drones can fly through ventilation shafts, access oil tanks, or inspect the roofs of tall buildings, capturing high-resolution imagery without exposing workers to risk. This not only reduces accidents but also helps companies comply with safety regulations, which is critical in high-risk industries. The Role of Drones in Improving Accuracy Another major benefit of industrial drone inspections is the enhanced accuracy they bring to data collection. Unlike traditional manual inspections, which are prone to human error, drones are equipped with precise GPS systems and sensors that capture highly accurate data. Drones can be equipped with thermal cameras to detect heat anomalies or LiDAR sensors for precise elevation measurements, giving inspectors more detailed and reliable data. This data is then used for accurate reporting, which supports better decision-making for maintenance, repairs, and upgrades. The ability to capture high-resolution terrain data and bathymetric data (underwater mapping data) further boosts the precision of drone inspections. Drones capture comprehensive, multi-angle imagery that is processed into 3D models and orthomosaics, giving teams a more accurate picture of their infrastructure. This level of detail and precision is crucial for industries like energy, construction, and utilities, where accurate data is essential for preventing failures and ensuring operational efficiency. As a result, companies can save time and money by addressing potential issues before they escalate. Data Reporting and Analysis Made Easy After completing a drone inspection, the next critical step is inspection data reporting. With drones, this process becomes more streamlined and efficient. The data collected by drones can be automatically uploaded to a cloud-based platform for analysis. Inspection data is then processed using specialized software, which converts raw footage into actionable insights. These reports are far more detailed than those generated by traditional methods, allowing teams to identify issues such as cracks, corrosion, or electrical malfunctions. In industries such as construction and infrastructure, detailed inspection data helps businesses make informed decisions about maintenance schedules, repairs, and replacements. This reduces downtime and keeps operations running smoothly. By providing clear, high-resolution images and 3D models, drone inspections make data reporting simpler and more effective, resulting in more informed decisions and better asset management. LiDAR Asset Inspection and Risk Reduction One of the most valuable aspects of LiDAR asset inspection is its ability to reduce risk in the inspection process. Whether it’s inspecting power lines, wind turbines, or buildings, drones can access dangerous areas without putting workers in harm’s way. For instance, powerline inspections traditionally required workers to climb utility poles or use helicopters, both of which carry significant risks. With drones, the risk of worker injury is minimized, and inspections can be conducted quickly without disrupting the power grid. By enabling more frequent and safer inspections, drones help prevent accidents and failures. Risk reduction with drones means identifying problems before they become serious. It ensures that assets stay in good condition and minimizes the likelihood of costly emergencies. This ability to proactively identify maintenance needs and mitigate potential risks is a major benefit for industries that rely on complex infrastructure. The industries include oil and gas, telecommunications, and transportation. How Drone Inspections are Revolutionizing Industries Drones are revolutionizing the way inspections are performed across various sectors. From infrastructure inspection drones to asset inspection by LiDAR, the benefits are clear. Drones increase safety, provide more accurate data, reduce operational downtime, and ultimately save money. In industries such as construction, energy, and manufacturing, drones have become indispensable tools for monitoring the condition of critical infrastructure. Companies can reduce the cost of hiring ground crews, avoid safety incidents, and
Beyond the Trees: How LiDAR Is Transforming Large-Scale Terrain Mapping
Mapping large landscapes has always been a challenge for surveyors and engineers. Dense forests, rugged terrain, and limited accessibility often make traditional surveying slow, expensive, and sometimes unsafe. For decades, gathering accurate data across large areas required teams on the ground navigating through vegetation and difficult conditions. Today, airborne LiDAR mapping is changing that reality. By using laser-based sensors mounted on aircraft or drones, LiDAR technology can capture incredibly detailed terrain information. From forestry planning to infrastructure development, LiDAR is redefining how professionals conduct large-area terrain surveys and create highly accurate digital models of the landscape. What Is Airborne LiDAR Mapping? Airborne LiDAR mapping uses laser pulses emitted from a sensor mounted on an aircraft or drone. These pulses travel toward the ground, bounce off surfaces, and return to the sensor. By measuring the time it takes for each pulse to return, the system calculates precise distances and generates millions of data points representing the terrain. These points form what is known as a point cloud, which is a highly detailed 3D representation of the landscape. Unlike traditional aerial photography, LiDAR can capture multiple returns from a single laser pulse. For example, the first return may reflect from the treetops, while later returns penetrate through branches and leaves to reach the ground surface. This capability allows LiDAR to reveal terrain that would otherwise remain hidden. The result is a highly accurate dataset that supports 3D terrain modeling, environmental analysis, and engineering design. Why Traditional Terrain Surveys Struggle in Forested Areas Traditional mapping methods struggle when terrain is covered by dense vegetation. Survey teams often need to physically access the site, which can involve clearing paths, navigating steep slopes, or working in remote environments. These challenges can lead to: Long survey timelines Limited coverage in difficult terrain Safety risks for field crews Incomplete data in heavily forested areas In regions with extensive tree cover, the actual ground surface may be almost impossible to measure using conventional techniques. This is where LiDAR offers a major advantage. Learn how Aerial Mapping services supports better planning decisions. Forest Canopy Penetration: Seeing Through the Trees One of the most powerful capabilities of LiDAR is forest canopy penetration. Because LiDAR sensors emit thousands of laser pulses every second, some of these pulses are able to pass through gaps in the vegetation and reach the ground below. This allows surveyors to collect elevation data even in areas with dense forest cover. By capturing multiple returns from each laser pulse, LiDAR can distinguish between different layers of the environment, including: Tree canopy Branches and vegetation Understory growth Ground surface This multi-layer data provides a complete view of the landscape—from treetops down to the terrain beneath. For forestry professionals and environmental scientists, this ability to see through vegetation is invaluable for understanding ecosystems and monitoring land changes. Vegetation Filtering with LiDAR Collecting raw LiDAR data is only the first step. Once the data is captured, specialized software processes the point cloud to separate vegetation from the ground surface. This process is known as vegetation filtering LiDAR. Algorithms analyze the point cloud and classify points into categories such as: Ground points Vegetation points Buildings or structures Water surfaces After classification, vegetation points can be removed or filtered out, leaving only the ground points behind. This enables surveyors to generate accurate bare-earth digital elevation models (DEMs). These filtered terrain models are essential for engineering applications such as road design, drainage analysis, and site planning. Conducting Large-Area Terrain Surveys Efficiently Another major benefit of LiDAR technology is its ability to cover large areas quickly. Traditional ground surveys may take weeks or even months to map extensive terrain. With LiDAR, aircraft or drone platforms can capture data across hundreds—or even thousands—of hectares in a fraction of that time. For example, airborne LiDAR systems can: Survey large forested regions in a single flight Capture millions of elevation points per square kilometer Map remote areas that are difficult to access on foot This efficiency makes LiDAR particularly valuable for large-area terrain surveys required in industries such as mining, forestry, and environmental management. Applications of LiDAR in Forestry and Environmental Studies The ability to collect detailed terrain and vegetation data has made LiDAR for forestry an essential tool for land managers and researchers. 1. Forest Structure Analysis LiDAR can measure tree height, canopy density, and forest structure. This data helps forestry teams understand forest health and monitor growth patterns. 2. Habitat and Ecosystem Monitoring By revealing both vegetation layers and ground terrain, LiDAR supports environmental studies related to wildlife habitats and watershed management. 3. Wildfire Risk Assessment Detailed vegetation data allows researchers to analyze fuel loads and assess wildfire risks in forested areas. 4. Sustainable Forest Management LiDAR datasets provide valuable insights that help forestry professionals make informed decisions about harvesting, conservation, and land use planning.

Speed and Coverage Large landscapes can be surveyed quickly, reducing project timelines and improving efficiency. 2. High Data Density Millions of elevation points provide extremely detailed terrain information. 3. Access to Remote Areas Aircraft and drones can map areas that are difficult or dangerous for ground crews to reach. 4. Vegetation Penetration LiDAR can capture ground data even beneath dense forest canopy. 5. Integration with Other Technologies LiDAR datasets can be combined with photogrammetry or satellite imagery to produce
Unlocking Hidden Waterways with Bathymetry
Waterways shape landscapes, support ecosystems, and influence infrastructure decisions. Yet the most important information about rivers, lakes, and coastal environments lies beneath the surface. That’s where a hydrographic bathymetric survey becomes essential. By using advanced sonar and geospatial technologies, bathymetry reveals the hidden contours of underwater terrain. It helps engineers, environmental scientists, and planners understand aquatic environments with precision. From inland water mapping to flood modeling and habitat monitoring, bathymetry provides the underwater data needed to make informed decisions. What Is a Hydrographic Bathymetric Survey? A hydrographic bathymetric survey measures the depth and shape of underwater terrain in rivers, lakes, reservoirs, and coastal areas. In simple terms, it is the underwater equivalent of a topographic survey on land. Specialized sensors capture underwater depth measurements and combine them with precise positioning systems such as GNSS. The result is a detailed model of the aquatic landscape, including riverbeds, lake floors, and submerged structures. These surveys support a wide range of applications, including: River mapping and lake mapping Floodplain analysis Infrastructure planning near water bodies Environmental and habitat monitoring Navigation safety assessments By transforming sonar readings into accurate digital models, bathymetry makes it possible to visualize underwater terrain with remarkable clarity. Why Is Inland Water Mapping Essential for Engineering Projects? Many engineering and environmental projects rely on accurate data about water bodies. However, traditional mapping methods often focus only on visible terrain, leaving critical underwater features undocumented. Inland water mapping fills this gap by providing detailed insights into underwater conditions. This information is essential for: 1. Flood Risk Management Riverbed shape directly influences water flow and flood behavior. Bathymetric surveys allow engineers to analyze channel depth, sediment buildup, and erosion patterns to better predict flood risks. 2. Infrastructure Design Bridges, dams, culverts, and pipelines all interact with waterways. Without accurate bathymetric data, designing these structures can become risky and inefficient. 3. Environmental Protection Aquatic habitats depend heavily on underwater terrain. Bathymetric data helps scientists understand habitat conditions and identify areas suitable for conservation or restoration. How Riverbed Mapping Technology Works Modern riverbed mapping technology combines multiple tools to collect and process underwater data efficiently. 1.

These compact vessels allow operators to safely collect data without entering hazardous waters. LiDARs are particularly useful in areas with: Strong currents Shallow channels Limited access points Environmental sensitivity 2. Echo Sounders for Depth Measurement Echo sounders are the core technology used in bathymetry. These instruments send acoustic pulses toward the waterbed and measure the time it takes for the signal to return. From this information, survey systems calculate precise underwater depth measurements. Modern echo sounders can collect data points multiple times per second, producing dense datasets that reveal underwater contours in great detail. 3. GNSS Positioning Systems Accurate positioning is critical for bathymetric data. Multi-band GNSS receivers record the exact geographic coordinates of each depth measurement, ensuring the resulting dataset aligns perfectly with land-based survey data. This combination of sonar depth readings and satellite positioning enables precise bathymetric data collection across large water bodies. From Raw Data to Aquatic Terrain Models Once field data is collected, it is processed to create detailed underwater maps and models. Survey software combines the depth measurements and positioning data to generate: Digital Elevation Models (DEMs) of riverbeds or lake floors Contour maps showing underwater depth variations 3D terrain models for visualization and analysis These outputs support aquatic terrain modeling, which helps engineers and scientists better understand underwater environments. When bathymetric data is integrated with LiDAR or photogrammetry surveys, the result is a seamless land-to-water terrain model. This combined dataset provides a complete picture of the landscape above and below the waterline. Contact us to learn more about Rekon’s bathymetric survey services.

Bathymetry The Missing Link in River Mapping
Rivers are constantly changing. Water levels rise and fall, sediments shift, and channels reshape over time. Yet many mapping projects still focus only on what is visible above the waterline. This leaves a major gap in understanding the true structure of a river system. Bathymetry fills that gap. It reveals the underwater terrain that influences flow patterns, erosion, flood risks, and infrastructure planning. Without bathymetry, river mapping is incomplete and decision making becomes less reliable. Across Canada, where rivers play a major role in transportation, forestry, energy, and environmental management, accurate bathymetry is becoming essential. What is bathymetry Bathymetry refers to the measurement and mapping of underwater terrain. It is similar to topographic mapping on land, but instead of hills and valleys, it captures the depth and shape of the riverbed or lake floor. River bathymetry helps engineers and environmental teams understand how water moves through a channel. It provides data on depth, slope, and underwater features such as sandbars, pools, and submerged structures. This information forms the foundation for hydraulic modeling, infrastructure design, and flood risk assessments. Why river mapping needs bathymetry Traditional river mapping often focuses on the banks and surrounding terrain. While this information is useful, it does not reveal what is happening beneath the surface. The shape of the riverbed directly affects Water velocity and flow direction Sediment transport Flood behavior Bridge and culvert performance Without river bathymetry, models and designs rely on assumptions rather than real measurements. This increases uncertainty and can lead to costly mistakes. How bathymetric lidar works Bathymetric lidar is a technology that uses laser pulses to measure underwater depth. Unlike standard lidar, which reflects off solid surfaces, bathymetric systems use green wavelength lasers that can penetrate water. The process works in two steps. First, a laser pulse reflects off the water surface. Second, part of that pulse continues through the water and reflects off the riverbed. By measuring the time difference between these two reflections, the system calculates the water depth and creates an accurate underwater terrain model. This approach allows for fast and efficient underwater terrain mapping across large river corridors. Advantages over traditional hydrographic survey methods Conventional hydrographic survey techniques often rely on boats equipped with sonar. While effective in certain conditions, these methods have limitations. They can be slow in shallow or narrow channels. Access can also be difficult in remote or hazardous areas. Bathymetric lidar offers several advantages Faster coverage over long river sections Reduced need for boats and physical access Safer data collection in remote or fast flowing areas Seamless integration with land based lidar data These benefits make bathymetric lidar especially valuable for large scale water depth mapping projects. Research insights on bathymetric mapping Recent research highlights the growing role of lidar in river studies. A study published in Journal of Hydrology found that lidar based river surveys improved the accuracy of hydraulic models by providing more detailed channel geometry. This led to better predictions of water flow and flood behavior.. Another research paper on small footprint green lidar showed that bathymetric lidar could successfully map riverbeds in clear water conditions while reducing the time required for field surveys. A remote sensing study also demonstrated that combining bathymetric lidar with aerial imagery improved overall terrain models in river corridors. These studies confirm that bathymetry is not just an added layer of information. It is a critical component of accurate river mapping. Applications of river bathymetry Bathymetric data supports a wide range of industries and projects. Infrastructure planning Bridges, culverts and pipelines often cross rivers. Accurate river bathymetry ensures these structures are designed with the correct depth and flow conditions in mind. Flood risk analysis Understanding underwater terrain helps predict how water will spread during high flow events. This is essential for floodplain mapping and community protection. Environmental monitoring Bathymetry reveals habitat conditions for fish and aquatic ecosystems. It also helps track erosion sediment buildup and channel changes. Forestry and resource corridors In forested regions, rivers often intersect access roads and utility lines. Water depth mapping ensures crossings are designed safely and efficiently. Learn how UAV inspections reduce downtime for industrial operations. Combining bathymetry with topographic data One of the greatest strengths of modern mapping is the ability to combine land and underwater data into a single model. By merging bathymetric lidar with standard lidar or photogrammetry, teams can create a complete representation of the river corridor. This integrated approach provides Continuous elevation models from riverbank to riverbed Improved hydraulic simulations Better planning for infrastructure and environmental projects The future of river mapping As climate patterns shift and infrastructure demands grow, accurate river data will become even more important. Bathymetry is no longer an optional layer. It is a fundamental part of understanding how rivers behave and how projects interact with them. Across Canada, organizations are adopting bathymetric mapping to improve flood modeling, environmental assessments, and infrastructure planning. Rekon Solutions supports these efforts by providing integrated mapping services that capture both land and underwater terrain. FAQs What is river bathymetry? River bathymetry is the measurement and mapping of the depth and shape of the riverbed. It helps engineers and environmental teams understand underwater terrain. What information is included in bathymetric data? Bathymetric data includes water depth, riverbed elevation, underwater features, and channel shape. How accurate is bathymetric mapping? Accuracy depends on the technology and water conditions. Modern bathymetric lidar systems can achieve high accuracy suitable for engineering and environmental applications. How to read a bathymetric map? Bathymetric maps use contour lines or color gradients to show depth. Closer contour lines usually indicate steeper underwater slopes.
Photogrammetry Turning Aerial Images into Precise 3D Models
Modern projects demand more than flat maps. Engineers, planners and developers now rely on detailed digital models to understand terrain structures and progress over time. This is where photogrammetry 3d models have become a powerful tool across construction infrastructure forestry and environmental projects. Photogrammetry transforms simple aerial images into accurate three dimensional representations of the real world. With the help of drones and advanced software, teams can capture vast areas and turn them into precise models for analysis and planning. What is photogrammetry? Photogrammetry is a method that creates three dimensional models from overlapping images. A drone or aircraft captures hundreds or thousands of photographs of a site from different angles. Specialized software then analyzes these images and calculates the position of every visible point. By identifying shared features across multiple photos, the system reconstructs the shape of the terrain or structure. This process produces detailed photogrammetry 3d models that can be used for measurement planning and visualization. How does drone photogrammetry work? Drone photogrammetry has made this technology more accessible and efficient. Instead of relying on manned aircraft or ground crews, drones can capture high resolution images quickly and safely. The process usually follows a few clear steps. First, the drone flies over the project area in a planned grid pattern. This ensures enough image overlap for accurate reconstruction. Next, the captured photos are processed through software that identifies matching points across images. Finally, the software generates 3d mapping from images, creating a digital surface model, orthomosaic, and full three dimensional representation of the site. This workflow allows teams to move from raw aerial photos to complete photogrammetry 3d models within a short time frame. The role of structure from motion At the core of photogrammetry lies a technique known as structure from motion. This method analyzes the movement and position of features across multiple images. As the software compares overlapping photos, it calculates how the camera moved between each shot. From this information it determines the spatial position of each point. The result is a dense point cloud that represents the shape of the landscape or structure. This point cloud is then converted into a surface model or mesh. Structure from motion is what makes aerial 3d reconstruction possible without needing direct distance measurements. Benefits of photogrammetry for large projects Photogrammetry offers several advantages that make it valuable across many industries. Fast data collection Drones can capture large areas in a short amount of time. This is especially useful for construction sites or infrastructure corridors where conditions change frequently. Detailed visual models Photogrammetric modeling produces highly realistic 3D visuals. These models help teams communicate plans and progress with stakeholders. Cost efficiency Compared to some other mapping technologies, drone photogrammetry often requires less expensive equipment. This makes it a practical option for many projects. Safe access to difficult terrain Drones can capture data over steep slopes, forests or active construction zones without putting survey crews at risk. Common applications of photogrammetry 3d models Photogrammetry is widely used across different industries. Its flexibility and visual clarity make it suitable for a range of tasks. Construction planning and monitoring Construction teams use photogrammetry 3d models to track progress, measure volumes and compare design plans with actual site conditions. Infrastructure development Road rail and utility projects rely on aerial 3d reconstruction to understand terrain conditions before construction begins. Forestry and environmental surveys In open forest areas or regions with moderate canopy cover, drone photogrammetry helps assess land features and monitor environmental changes. Mining and stockpile measurement Mining operations use photogrammetric modeling to calculate stockpile volumes and monitor site activity. Accuracy in photogrammetric modeling Accuracy in photogrammetry depends on several factors. Image quality and resolution Overlap between photos Flight planning and altitude Ground control points When these factors are managed correctly, photogrammetry 3d models can achieve high levels of accuracy suitable for planning and measurement. However, dense vegetation or uniform surfaces may reduce reliability. In such cases, other technologies like LiDAR may be considered. Photogrammetry compared to other 3d mapping methods Among different 3d mapping methods, photogrammetry stands out for its visual detail and efficiency. It is particularly effective on open construction sites, urban areas and projects where visual context matters. Teams can see textures, colors and real world features directly in the model. While other technologies may provide stronger performance under heavy vegetation, photogrammetry remains a versatile and cost effective solution for many mapping tasks. Learn why LiDAR is now the industry standard. Why photogrammetry continues to grow in popularity Advancements in drone technology software processing and computing power have made photogrammetry more accessible than ever. Projects that once required weeks of fieldwork can now be mapped in a single day. The ability to generate accurate and visually rich photogrammetry 3d models has changed how teams approach planning and analysis. Across Canada, construction and infrastructure projects increasingly rely on aerial data to improve efficiency and decision making.

Save the Salmon! Bathymetry in a Hydrological Study
In this post we will take a look at how the fires that ravaged the East Adams Lake area in 2023 threatened to potentially destroy precious Salmon breading grounds in the Lower Adams River, and the work that is still being done to mitigate the damages and hopefully improve the Salmon Run for years to come. The 2023 Wildfires 2023 saw one of the most destructive wildfire seasons in British Columbia’s recorded history, with more that 2.84 million hectares of forest and land burned, tens of thousands of people forced to evacuate and hundreds of homes and structures lost or damaged. With the Adams Lake complex fire measuring over 10,004.9 hectares at its peak, and surrounding the Lower Adams River on all sides, the damage to the forests vegetation could cause serious erosion issues in the event of heavy rainfall. When a wildfire burns through an area, it burns up most if not all vegetation, leaving the soil compromised not able to absorb the moisture of a heavy rainfall. If you couple this scenario with steep terrain, the water that is not absorbed can run and carry debris with it. This water and debris all flow and settle in the river systems. This erosion would severely impact the Lower Adams River and would pose a serious risk to a large population of salmon that rely heavily on this section of river for their annual spawning grounds. The Salmon Run “A salmon run is an annual fish migration event where many salmonid species, which are typically hatched in fresh water and live most of their adult life downstream in the ocean, swim back against the stream to the upper reaches of rivers to spawn on the gravel beds of small creeks.” – wikipedia The Lower Adams River is one of the largest annual spawning grounds in BC for several Salmon species. In the third week of August, the late-run sockeye salmon run alone was estimated to be nearly 4.5 million returning to the Lower Adams River spawning grounds. With such a large population of Salmon dependent on this river system something had to be done to protect the Salmon’s spawning grounds. To answer the call for action was the Skwlāx First Nations Band. Skwlāx te Secwepemcu’lecw (formerly Little Shuswap Lake Band) The Skwlāx First Nations Band is centered in and around the Lee Creek area and pride themselves on being stewards and protectors of the land. It was the bands approved funding that put in motion the wheels for change. The band put together a project task force comprised of Band leaders, community leaders, project managers, engineering staff, Department of Fisheries staff and drone LiDAR subcontractors to assess, diagnose and troubleshoot a path forward. Working with the Skwlāx First Nations Band, the task force experts first needed to conduct a Hydrological Study of the Lower Adams River to assess the risk level, engineer mitigation measures and possibly even produce a plan to increase the Salmon’s spawning grounds by potentially opening up older dry channels in the river system. In order to conduct the Hydrological study the engineers required accurate topography data of the Lower Adams River as well as the surrounding area. In order to provide accurate data for the Hydrological study, Rekon was tasked to deploy Drone LiDAR Mapping to produce an accurate topographic survey of the surrounding area as well as Drone Photogrammetry Mapping to produce a high accuracy Orthomosaic Map. While LiDAR is great at topographic surveying, even in dense vegetation, LiDAR does not return data in water (the laser light is reflected on the surface of the in water) thus, creating missing data in the survey. Which isn’t ideal for a Hydrological Study. Good thing there is such a thing as Bathymetry. Bathymetric Survey This section will take a look at how Rekon used their Bathymetry system to survey the Lower Adams River floor elevations to “fill in” the missing river sections of topography data from the LiDAR survey. But first, what is Bathymetry? Wikipedia describes Bathymetry as “the study of underwater depth of ocean floors (seabed topography), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography“. For visual representation, see the image below from an article in LiDAR Magazine “Overcoming Hurdles to Modeling River Bathymetry”. Check it out the article here! Example image of river bed topography (image supplied by https://lidarmag.com/2019/05/08/overcoming-hurdles-to-modeling-river-bathymetry/) The first component to collecting bathymetry data is the vehicle. At Rekon we deploy an Unmanned Survey Vehicle, or USV made by Bathycat, designed to complete bathymetric surveys with a single beam echo sounder while remaining safely on the shore or river banks. This catamaran style USV is remotely piloted with two forward and reverse thrusters that can carry out manual maneuvering or automated missions. The second component to collecting bathymetry data is the depth measuring device or sensor. Integrated into the Bathycat is a survey grade 200kHz single beam echo sounder, capable of collecting data points at a ping rate of 1Hz – 10Hz (1-10 soundings per second) from a minimum depth of 0.4m (1.3 ft) up to 100m (328ft) deep. It is also capable of being mounted on other watercraft such as kayaks, rafts or motorized boats which allows us to choose the right watercraft for the waterway so we can collect accurate data safely. The third component of collecting Bathymetry data is the GNSS receiver or GPS survey receiver. This multi-band RTK GNSS receiver is capable of centimeter precision and communicates via Wifi with the Bathycat onboard computer to record position data along with the elevation data from the echo sounder. Data Collection In the planning phase of the project, the Bathymetry missions were created to ensure adequate coverage of the river in approximately 5-10m cross sections, as seen below. However the urgency of project, the water levels, partly submerged obstacles and swift current of the Lower Adams River meant collecting the data while operating the USV fully manual was the safest choice.

Aerial Mapping Services: How Drone Data Supports Better Planning Decisions
In the past, creating accurate maps of large areas was time-consuming, expensive, and sometimes dangerous. But with the rise of drones, aerial mapping has entered a new era. Drones have revolutionized how we collect and analyze data, offering an efficient and cost-effective way to gather detailed information from the sky. If you’ve been curious about how drone data is supporting better planning decisions, you’ve come to the right place. Let’s take a closer look at how drone aerial mapping works, the benefits it brings to various industries, and why UAV mapping services are becoming the go-to solution for projects big and small. What is Aerial Mapping? At its core, aerial mapping involves using aircraft or drones to capture images or data from above. These images and data are then processed into maps, models, and other forms of useful information. Traditionally, this was done with manned aircraft, but now mapping by drones is the preferred method for its precision, efficiency, and cost-effectiveness. UAV mapping services can create 2D maps or 3D aerial maps that show terrain, buildings, vegetation, roads, and much more. These maps can be used for a wide range of applications, from urban planning to environmental monitoring, and even construction site management. The Benefits of Drone Mapping 1. Speed and Efficiency One of the biggest advantages of drone aerial mapping is speed. Traditional mapping methods, especially for large areas, could take days or even weeks. With drones, the same area can be mapped in just a few hours. Drones are equipped with cameras and sensors that capture data from every angle, creating a comprehensive view of the land in less time. This speed doesn’t just save time; it also saves money. Less time spent on the field means lower labor and equipment costs, making UAV mapping services more affordable. 2. High Accuracy Accuracy is crucial when it comes to planning projects, whether you’re designing a building, laying out a road, or assessing an environmental area. GIS aerial mapping and 3D aerial maps created by drones offer incredibly precise data. By using GPS technology and advanced software, drones can achieve centimeter-level accuracy, making them perfect for tasks that require high precision. For example, a drone aerial mapping of a construction site can provide exact measurements, helping architects and engineers make better decisions. 3. Access to Hard-to-Reach Areas Some areas are difficult or dangerous to reach, making traditional surveying methods a challenge. Think about surveying steep mountain slopes or dense forests. Mapping by drones is the solution. Drones can easily fly over these difficult terrains, collecting data without requiring surveyors to put themselves in harm’s way. For example, airborne LiDAR BC (a LiDAR-based technology) uses drones to scan terrain, even through vegetation, giving surveyors a detailed, accurate picture of the land. 4. Real-Time Data Collection Drones provide real-time data, which means you don’t have to wait for days to get the results of your survey. As the drone flies over the area, the data is instantly sent to the ground station, where it’s processed and analyzed. This allows for immediate decision-making, which is critical in fast-paced industries like construction and urban planning. 5. Cost-Effective As we mentioned, UAV mapping services save both time and money. Traditional methods require a large team, expensive equipment, and a lot of labor. Drones, on the other hand, are more cost-efficient and require less manual labor. The upfront cost of purchasing or renting drones is quickly offset by the savings in time and labor. How Are Drones Used for Mapping? 1. Urban Planning and Development Drone aerial mapping is a game-changer for urban planning. City planners and developers can use drones to create accurate maps of existing land, infrastructure, and even future development areas. This data helps them plan roads, buildings, parks, and other infrastructure with a high degree of precision. Drones are especially useful when mapping large areas of land that will be developed in stages. With UAV mapping services, city planners can continuously monitor the progress of construction, make adjustments as needed, and ensure everything stays on track. 2. Environmental Monitoring Another area where drone aerial mapping excels is in environmental monitoring. Drones can be used to map forests, wetlands, or coastal areas, providing valuable data on the condition of ecosystems. For example, GIS aerial mapping can track changes in vegetation, water bodies, or even soil erosion. These maps help environmental organizations monitor land use, assess the impact of climate change, and make informed decisions about conservation efforts. Drones provide a more efficient and less disruptive way of monitoring the environment compared to traditional methods, which can require heavy machinery and a lot of personnel. 3. Construction and Infrastructure In construction, 3D aerial maps are used to map sites before construction begins. These maps help in designing the layout of roads, buildings, and utilities. During construction, drones can be used to monitor progress, ensuring the work is on schedule and within budget. Additionally, drones can be used to monitor infrastructure such as bridges, powerlines, and communication towers. With drone surveying applications, these structures can be inspected quickly and accurately without the need for workers to climb or enter dangerous areas. 4. Agriculture Farmers are increasingly using drone mapping for crop monitoring. By using drones equipped with multispectral sensors, farmers can track crop health, monitor irrigation systems, and assess soil conditions. Drones help farmers detect early signs of disease or pests, allowing them to take action before significant damage is done. This real-time data helps farmers optimize their crop yields while minimizing the use of pesticides and water, leading to more sustainable farming practices. 5. Mining and Resource Management In the mining industry, drone aerial mapping is used to monitor stockpiles, map mine sites, and track progress. Drones help mining companies save time by providing quick and accurate data on the size of stockpiles, the layout of the site, and the volume of material extracted. These maps help managers make more informed decisions, from managing resources to planning future mining operations. What Is the
Mine Surveying With Drones: Faster Data, Higher Accuracy, and Safer Operations
Mining has always been one of the most data-heavy industries in the world. Whether it’s calculating volumes, planning excavation, or ensuring worker safety, every decision depends on accurate data. That’s where drone technology steps in. Today, mine survey operations are faster, safer, and more accurate than ever before thanks to mine mapping drones and UAV mine survey methods. So, how exactly are drones changing mine surveying, and why are companies in Canada and around the world making the switch? Let’s explore. What Is Mine Surveying and Why Does It Matter? Mine surveying is the process of measuring, mapping, and analyzing the surface or underground layout of a mine. It helps determine the volume of materials extracted, track site progress, and ensure compliance with safety and environmental regulations. Traditional mine surveys often require workers to physically enter hazardous areas to take measurements. This not only takes more time but also increases risks. Drones, however, allow teams to perform accurate surveys from the air, enuring that the process is quicker, safer, and much more efficient. How Drones Are Transforming Mine Surveys 1. Faster Data Collection In the past, surveying large mine sites could take days or even weeks. With mine mapping drones, teams can now capture detailed aerial data in just a few hours. Drones equipped with high-resolution cameras and LiDAR sensors can cover large areas in a single flight, collecting thousands of data points. For example, A recent study in the Journal of Archaeological Science highlights how drone photogrammetry can decrease data acquisition from several hours or days to mere minutes, covering larger areas with high-resolution imagery and data Therefore, mining companies can make faster decisions and keep their operations running smoothly without long pauses for survey work. 2. Higher Accuracy With LiDAR and Photogrammetry Modern drones are equipped with mining LiDAR technology and photogrammetry sensors that generate detailed 3D models of mine sites. These models allow engineers to measure distances, calculate volumes, and identify changes in terrain with pinpoint accuracy. LiDAR sensors can capture precise elevation data even in areas covered by vegetation or debris. Resultantly, mine planners can identify potential hazards, design safer excavation routes, and plan stockpile movements more accurately. For more on how LiDAR improves data collection, you can read our previous blog on LiDAR services in Canada. 3. Enhanced Safety for Workers Mine sites are often filled with risks such as steep slopes, unstable ground, and heavy machinery. Traditional mine surveying exposes workers to these dangers. With UAV mine survey techniques, drones can safely access these high-risk areas and collect the required data without putting surveyors in harm’s way. Therefore, mining companies can maintain high safety standards while still getting the accurate measurements they need. As a result, fewer people need to enter hazardous zones, reducing both risk and downtime. 4. Accurate Volumetric Analysis Calculating how much material has been extracted or how much remains in a stockpile is one of the most critical parts of mine surveying. Volumetric analysis using drones provides far more accurate results than manual methods. Drones can generate 3D models that allow precise calculation of volume changes over time. This helps mine operators monitor progress, plan future excavation, and ensure they’re meeting production targets. 5. Simplified Stockpile Measurement Keeping track of materials on-site is another major challenge in mining. Manual stockpile measurements often require workers to climb piles or use heavy equipment to estimate volumes. This is not only slow but also dangerous. With drone-based stockpile measurement, a single flight can capture detailed topographic data of multiple piles at once. Afterwards, advanced software processes the data into accurate 3D maps. This allows mine managers to monitor material inventory in real time, to make reporting and compliance much easier. 6. Real-Time Monitoring and Reporting Another major advantage of mine mapping drones is their ability to provide real-time updates. After each flight, drones send data directly to processing software that creates detailed 3D maps and orthophotos within hours. This means managers don’t need to wait days to access reports. They can review current site conditions almost instantly. As a result, decisions can be made faster, and problems can be identified before they become costly. 7. Cost Savings Over Time Switching to UAV mine survey methods doesn’t just save time, it also reduces costs. Fewer staff are needed on-site, insurance and safety costs go down, and operations experience less downtime. The initial investment in drone technology pays off quickly. Although the upfront expense may seem high, the long-term benefits make it a smart financial move for mining operations. The Role of Mining LiDAR in Underground and Surface Surveys LiDAR technology has become one of the biggest advancements in modern mining. By sending thousands of laser pulses per second, LiDAR sensors create extremely accurate 3D representations of both surface and underground mine areas. For surface operations, mining LiDAR can map terrain, track changes in slopes, and identify erosion. Underground, it helps map tunnels and shafts where visibility is limited. These precise 3D models improve safety and assist engineers in designing efficient extraction plans. Therefore, LiDAR not only improves accuracy but also gives mining teams a deeper understanding of their site’s physical conditions — helping them make safer and smarter decisions. How Drones Support Environmental Compliance Mining operations must follow strict environmental guidelines. Drones make it easier to comply by offering accurate data for environmental assessments and rehabilitation tracking. Through mine survey data, companies can monitor land changes, water flow, and vegetation impact around their sites. Furthermore, drones help track land reclamation progress after mining is complete. Resultantly, companies can ensure they meet environmental restoration goals and maintain transparency with regulators. ]Partner With Us for Aerial Mine Surveying As drone technology continues to evolve, Rekon Solutions is helping mining companies across Canada collect accurate, reliable, and cost-effective data.
