ASP output files

What the key files in an ASP run directory mean. Most are named with a RUN_PREFIX- followed by a fixed suffix. This is not every file, just those we are most interested in; the ASP output files docs describe everything.

After bundle_adjust -o ba/run

File	Contents
ba/run-clean.match	Final matches between images (binary)
ba/run-initial_residuals_pointmap.csv	Per-match reprojection residuals before optimization
ba/run-final_residuals_pointmap.csv	…after optimization
ba/run-IMAGE.adjust	Per-image camera adjustment (small text file)
ba/log-bundle_adjust-*.txt	Full log; ASP version, command line, runtime

After mapproject

File	Contents
IMAGE.map.tif (or whatever you named it)	Image resampled onto reference DEM grid

After parallel_stereo -o stereo/run

File	Contents
stereo/run-L.tif, run-R.tif	Preprocessed left/right images
stereo/run-lMask.tif, run-rMask.tif	Per-image masks
stereo/run-D.tif	Initial disparity from correlation, in whole-pixel shifts
stereo/run-RD.tif	Disparity after subpixel refinement
stereo/run-F.tif	Final disparity after outlier filtering; the input to triangulation
stereo/run-GoodPixelMap.tif	Gray where the correlator matched, red where it failed
stereo/run-PC.tif	Point cloud (4 bands: x, y, z as offsets from a local origin, and ray intersection error)
stereo/run-stereo.default	Snapshot of stereo parameters used
stereo/log-stereo-*.txt	Per-stage log files

run-D.tif, run-RD.tif, and run-F.tif are successive versions of the same disparity map, all in one format: three bands holding the horizontal shift, the vertical shift, and a good-pixel mask. A run leaves further intermediates in the same format, such as run-D_sub.tif (the low-resolution disparity that seeds run-D.tif) and run-B.tif (run-D.tif blended across processing tiles).

After point2dem

File	Contents
stereo/run-DEM.tif	The DEM. Single-band float32, georeferenced.
stereo/run-DRG.tif	Orthoimage at the same grid (if --orthoimage)
stereo/run-IntersectionErr.tif	Intersection error gridded onto the DEM (if --errorimage)
stereo/log-point2dem-*.txt	Log

After pc_align

File	Contents
align/run-trans_source.tif	Source point cloud after alignment (in reference frame)
align/run-transform.txt	4×4 rigid transformation matrix
align/run-inverse-transform.txt	Inverse, for going back
align/log-pc_align-*.txt	Log with begin/end percentile errors
