Most often UAV data is acquired to have a single overview of the area of interest through stitching of several images that are corrected for the terrain/topographic effects called ortho-mosaicking. This requires post-processing of the data using specialized software. Terrain is estimated from 3D point clouds generated through photogrammetric procedures (image matching) on the overlapping images. There are multiple challenges associated with processing of imagery acquired using a UAV for generating an orthomosaic.
