Description
Concurrent Imagery – The imagery was processed in an independent parallel workflow. PhaseOne camera data was downloaded, developed, and inspected. Applanix processing software was used to obtain a Smoothed Best Estimate Trajectory (SBET), and export orientation parameters for each frame. Agisoft Metashape was used for aerial triangulation - to orient the block; point cloud DSM generation; image rectification and mosaicing. The resulting ortho-rectified imagery was reviewed and manually edited where required. Comparison to the ground control was made to detect and correct for any bias. Colour profiling, image tiling and final QA completed the Imagery process, and the orthophotos were then supplied to the LiDAR team to colourise the Point Cloud.
