How to use it

1. download SRTM or Copernicus DSM in your area and refer it to WGS84
2. edit asp_parameter.txt file (example available in example directory)
3. edit pair-list file (example available in example directory): list_pairs.txt
4. run orthorectification and stereo: launch_stereo_pleiades.sh -n list_pairs.txt
5. run post-processing check: check_process.sh list_pair.txt
6. run mosaic multispectral images: launch_MS_pleiades.sh -n list_pairs.txt
7. run alignement of two DSM and difference computation for error estimation: launch_align_diff.sh -n list_align.txt (see example/list_align.txt)
8. run error estimation: dem_error_estimation.py --diff=diff-6703445101-6703446101-6708224101-6708225101/diff-dsm.tiff --slope=diff-6703445101-6703446101-6708224101-6708225101/dsm-slope.tiff --name=Oman
9. get nan pixel ratio with plot: dem_nan_ratio.py --data=6620390301-6620391301/dsm_denoised_filtered.tiff --p
10. run corr_eval: dem_corr_eval.sh -n list_pairs.txt
