Description
Raw imagery was evaluated using Leica's FPES and Xpro software with the estimated accuracy of 2 pixels. AT was performed using GNSS+IMU observations and without aerial Ground Control Points. An auto correlated point cloud is created using the Semi Global Matching SGM process using 3 PAN channels bands backward, nadir and forward 1:1 10cm GSD. Then the SGM point cloud is gridded to a 5m Digital Surface Model DSM. The DSM is then manually edited to remove building, low and sparse vegetation and other above ground objects that can cause distortion in the ortho-generation. The DSM is used to generate the Level 2 L2 imagery. Leica's Xpro software was used to rectify geocoded raw L0 ADS imagery to orthorectified L2 imagery using a Fugro generated SGM DEM. Inpho's Orthovista was used to mosaic and colour balance the imagery. Adobe Photoshop was used to edit and batch enhance the final output. ER Mapper was used to generate the final output deliverables.
