Description

1. Imagery downloading and QA/QC of raw data; 2. Geo-referencing the ADS80 imagery using the precise flight trajectory from GNSS-IMU post-processing; 3. Automatic measurement of tie points between the images (APM) and combined block adjustment; 4. An auto correlated point cloud was created using the SGM process in XPRO. Then filtering algorithms were optimized to produce ground surface. 5. The ground filtered dataset was then visually checked by an operator, and incorrectly classified data was corrected or the ground filtering algorithm is adjusted and then visually checked; 6. Ortho-rectification resulted Level 2 (L2) images; 7. Inpho's Orthovista software was used to mosaic, colour balance the imagery and create the output mosaic (in GeoTIFF Tiles); 8. Adobe Photoshop was used to edit and batch enhance the final output
