Drone to DEM: Method for UAS data acquisition assimilation into GIS
Track: 3D Mapping
Authors: Robert Garst

Using a hobby grade UAS and a small action camera as a remote sensing platform, a number of topographic products have been derived. These products include a detailed orthometric mosaic, DEM, and a point cloud. The method 'structure from motion' (SFM) is employed in the creation of these products and requires an image overlap (at least 60%) to perform the bundle adjustment. The images and ground control points are the only source data required to generate these topographics.
