TopoFlight is a 3d flight planning software which allows the fast and interactive design of flight plans. The inclusion of digital elevation models leads to best results and minimizes the amount of images and thereby the costs of any flight mission. Different export interfaces allow an eays transfer to almost any flight managment system. TopoFlight can be used to plan photogrammetry and LIDAR missions and supports frame, line and LIDAR sensors. TopoFlight calcaulates the project costs and presents the results as maps and tables what symplifies the quotation generation.
