Does a large shadow impact the accuracy of a point cloud generated using photogrammetry? We explore a sample data set to see if and how much.

Purpose

This brief is to cover at a high level the problem posed by tree canopies when attempting to generate a DEM using photogrammetry.  Photogrammetry is based on images and therefore can only derive data from what is ‘seen’ by the camera.  Consequently, if all the c...
