Continuing to receive emails from users who are using input DEMs in EPSG:4326. Simple solution is to exit with message about reprojecting with gdalwarp. Maybe add a `-t_srs` option to...
I started this process with the HYDROBasins products for lakes/rivers (https://github.com/dshean/demcoreg/blob/master/demcoreg/get_hydro.sh) but never actually added support in the `dem_mask` functionality. Should be pretty straightforward - can use the RGI polygon...
Ideally, we would fetch all of these layers (e.g., NLCD, bareground) on the fly through services like "Earth on AWS" registry: https://aws.amazon.com/earth/ At present, they still require local download, extraction...
Can add `pip install` steps, which should simplify setup. Should also review and remove unnecessary dependencies. Likely requires a full review of pygeotools as well. Not sure we need `imview`...
The initial `dem_align.py` planar fit to remove post-co-registration residuals worked well. The current n-order polynomial fit functionality is largely untested. User reports in Dec 2019 indicated this functionality is not...
