This directory contains detailed READMEs for each step of the rectification process. See below for a short description:
- 0_preparation.md: setup of required software and data
- 1_stitching.md: stitching of the 2 (or more) partial GeoTIFF scenes into one single GeoTIFF (applicable for CORONA; HEXAGON and GAMBIT scenes) OR
- 1_automatic_stitching.md: automatic stitching for CORONA and HEXAGON scenes with a maximum of 4-5 scene pieces (scenes with more pieces will need >60GB RAM)
- 2_cropping.md: crop the raster to an extent where only relevant image pixels are left and residual pixels from the physical film scan are removed
- 3_gcp_collection.md: identification of GCPs between unrectified scene and reference data
- 3.1_gcps_overlapping_scenes.md: additional hints for GCP collection of an entire swath of scenes
- 4_orthorectification.md: orthorectification of CORONA and HEXAGON scenes (incl. correction of panoramic distortion)
- 4_georectification.md: georectification of GAMBIT scenes (no correction of panoramic distortion required)
