AeroTopoL is Software-Solution for Mission Planning and Flight Management for aerial imaging. AeroTopoL is the only operational GIS-based Mission Planning and Flight Management-System on the market. Beside full GIS functionality, it uses a Wizard to be very user-friendly. AeroTopoL enables many im- and export formats for raster and vector data as well as many coordinate systems. Data of different geodetic datum can be re-projected on the fly. Analysis of overlaps during planning helps with mission planning to predefine best places for GCPs. AeroTopoL supports any frame based analogue or digital camera and calculates the accuracy of the project. With AeroTopoL-DTM the terrain is taken into account in computing adjusted footprints.
