Adaptable Flight Line Planning for Airborne Photogrammetry Using DEM
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Flight line planning is the first step in an aerial photography campaign. Its two key parameters, ground sampling distance (GSD), and overlap should be designed carefully as they will impact subsequent flying workload and even the final mapping accuracy.
