16.54. pc_mergeΒΆ

This is a simple tool for combining multiple ASP-generated point cloud files into a single concatenated file. The output file will be float32 unless the input images are float64 or the user has specified the float64 option.

pc_merge can merge clouds with 1, 3, 4, and 6 bands. In particular, it can merge output-prefix-L.tif images created by stereo. This is useful if it is desired to create an ortho-image from a merged cloud with point2dem. In that case, one can invoke pc_merge on individual L.tif files to create a merged texture file to pass to point2dem together with the merged point cloud tile.
