Missing requirement: demtools/stats.py #5

Closed tania80 closed 6 years ago

tania80 commented 6 years ago

Hello, I'm trying to use the dem_coreg.sh script, and the execution fails on line 94 with the error 

/home/USER/src/demtools/stats.py: No such file or directory

I could not find in the README or documentation which demtools should be used to complete the functionality.

Thanks for any information.

Hi! The package (demtools) you are referring to is not public at this moment. For this particular problem, you can replace the stats.py by robust_stats.py tool, which you get when you install the demcoreg package. Moreover, if you are coregistering 2 dems, you might also want to have a look at the newly updated "nuth and kaab" implementation in dem_align.py (https://github.com/dshean/demcoreg/blob/master/demcoreg/dem_align.py)

Hi @tania80 I pushed some changes to dem_coreg.sh to use robust_stats.py to get the count of valid pixels. As @ShashankBice suggested, the dem_align.py tool might be a good option if you are working with two gridded rasters. If you are working with point cloud data, you will want to use pc_align. The dem_coreg.sh script is something of a custom wrapper for my application, which uses some nontrivial masking steps. You might also consider using ASP pc_align directly, and can consult the ASP manual for more details. Hope that helps.
