Our LiDAR Solutions
Our LiDAR solutions are cost-effective and cover a large Area of Interest (AOI) in less time. They easily collect LiDAR, digital ortho-imagery, and stereo imagery in one flight mission. This data can be used to build an accurate elevation model and can be compiled and processed into detailed bare earth models. Imagery derived from LiDAR can be processed into several types of models, including digital elevation models (DEM), digital surface models (DSM), digital terrain models (DTM), and topographic maps. With an extremely high density of points per square meter (50-100 ppsm), we can build highly accurate models of the earth’s surface.
Acquisition
We review our clients’ goals and analyze the area of interest (AOI), making crucial decisions on whether to use a drone or an aircraft for the project scope. Before flying, CompassData follows a rigorous checklist to ensure the safety, reliability, and efficiency of our pilots and field crew. Once project details are finalized, ground control targets are set and surveyed according to procedures aligned with ASPRS standards. This ensures that our products meet all accuracy requirements desired by our customers.
Post-Processing
CompassData’s team includes post-processing professionals who have the expertise to ensure Quality Control/Quality Assurance for LiDAR deliverables. Postprocessing from CompassData includes all relevant LiDAR attributes: classification, intensity, return information, GPS timestamp, flight line information, etc. We have the expertise to post-process any LiDAR to professional standards.
Quality Assurance / Quality Control
CompassData offers calibration capability for LiDAR data, with leading software tools, prior to using crucial Quality Control procedures for testing and reporting both, absolute positional accuracy as well as the relative accuracy among all datapoints. While independently derived Ground Control Points are a crucial component for LiDAR quality, calibration can be a complicated procedure. We can provide the GCPs for your in-house calibration, or we can do Quality Control for you, using our proprietary GCPs and a least-squares minimization technique designed to ensure the best calibration quality. Our QA/QC quantitative check ensures vertical accuracy, horizontal accuracy, clustering of points, and nominal posting. We will meet ASPRS standards for collection.
