Following a catastrophic wildfire in New Mexico, monsoonal debris flows clogged stream channels and destroyed infrastructure. While scoping the project, we worked closely to understand the data needs of our customer and select the sensor type and UAS platform most appropriate for the project and site. By comparing high-resolution UAS lidar-measured elevation products with pre-event lidar sources, RedCastle Resources was able to estimate the depth and volume of eroded and deposited sediment with <10 cm vertical accuracy. Our analysts’ expertise in every step of the lidar processing pipeline and their familiarity with other remote sensing data sources allowed us to deliver on this project, providing change estimates, DEMs, DSMs, hydrological analysis, and aerial imagery.

Riparian ecosystems are among the most diverse and important ecosystems but are also among the most threatened habitats in our everchanging world. Natural and anthropogenic changes, such as flooding, drought, wildfire, cattle grazing, and urban development can quickly alter a riparian corridor and threaten the fauna and wildlife that depend on it. For such high-risk sites, we use UAS technology to timely capture high-resolution thermal and natural color imagery for the use of monitoring and detecting changes. UAS thermal cameras allow us to detect cold and hotspots in rivers to assess for threats to trout habitat, and natural-color cameras provide the detail needed for mapping streambank erosion, riparian vegetation, rifle-pool systems, and presence of woody debris. This information enables us to provide real-time information to make informed decisions when it comes to supporting these dynamic ecosystems.

With over 300 pilots trained in mapping, our UAS mapping course covers essential topics such as camera settings, optimizing flight configurations, using flight planning software, conducting flight operations, ensuring accuracy, and processing data to deliver precise results—all while maintaining FAA compliance and safety. We also provide specialized training on advanced sensors, including thermal, multispectral, and lidar technologies. Our training leverages the expertise of our experienced pilots to provide your organization with the tools to conduct your own UAS work.

Highly detailed terrain and imagery provides critical information for safety and sustainability. We conducted a comprehensive aerial lidar and imagery survey covering 1,800 acres across three active mining sites and two geohazard sites near Bozeman, Montana and West Yellowstone, Wyoming. Utilizing a UAS-based lidar sensor, we captured high-resolution elevation data and imagery. This centimeter-level accuracy dataset allows stakeholders to understand the terrain and vegetation to minimize environmental disturbances, identify potential hazards, and implement mitigation measures to ensure safety. This data supports the effectiveness of remediation efforts and helps optimize long-term stability.
