Maximize Survey Accuracy with UAS LiDAR Technology

Bolton & Menk recognizes the importance of investing in new technologies to help our clients save time and money. Our in-house professional surveyors and FAA Certified UAS pilots work side-by-side to ensure the most accurate data results using the latest technology—UAS LiDAR.

The UAS pilot collects aerial 3D data using light detection and ranging (LiDAR) sensor integrated with a camera. Low altitude LiDAR data collections provide high-density data with multiple returns, delivering high accuracy ground terrain models. Aerial photography collected simultaneously to LiDAR is used to colorize LiDAR point clouds and can be processed into up to date, ortho-rectified base map imagery with spatial resolutions of roughly 1.5 inches.

Under the direct supervision of a professional land surveyor, survey staff work with our UAS professionals to set a network of horizontal and vertical aerial control targets. Next, the LiDAR flight is performed, processed, and reviewed for quality and accuracy. The LiDAR data is then reduced to extract a digital terrain model and any topographic information required. Finally, the LiDAR extracted topographic data is reviewed using a set of independent survey established ground checks and any supplemental data is collected using conventional survey methods to fill areas that might be obscured in the LiDAR data. LiDAR data can be imported into design software like traditional topo survey, and surfaces and TINs can be built from the dense and accurate point cloud.
