The Bureau of Land Management (BLM) National Operations Center Geospatial Imaging section (OC534) requires a drone-mountable Lidar scanning solution to facilitate the field-based documentation and characterization of various natural and cultural resources. The system must be compatible with planned aircraft (Freefly Astro), have a significant range (i.e. support flight up to 100 m above ground level) and point density (160+pts/sqm at 100m AGL and 10m/s), and, ideally, should be compatible with existing Yellowscan software in use by the Department. One complete system/unit is required, including necessary software for processing scans.
