Evaluation of pushbroom DAP relative to frame camera DAP and lidar for forest modeling

open access: yesRemote Sensing of Environment, 2020
Abstract There is growing interest in using Digital Aerial Photogrammetry (DAP) for forestry applications. However, the performance of pushbroom DAP relative to frame-based DAP and airborne lidar is not well documented. Interest in DAP stems largely from its low cost relative to lidar. Studies have demonstrated that frame-based DAP generally performs
