Some that may overlap with geoutils/xdem are (by order or priority):
rioxarray: geospatial xarray extension powered by rasterio - a lot of overlap with geoutils. See if it would make sense to merge.
xarray-spatial: Numba-accelerated raster-based spatial processing tools (NDVI, curvature, zonal-statistics, proximity, hillshading, viewshed, etc.) - seem to also have quite some overlap with xdem.
pyinterp - Seem to have accelerated tools for spatial interpolation and binning.
salem: Adds geolocalised subsetting, masking, and plotting operations to xarray’s data structures via accessors. - Check directly with Fabien :wink:
Regionmask: plotting and creation of masks of spatial regions
GeoWombat: Utilities for analysis of remotely sensed and gridded raster data at scale (easily tame Landsat, Sentinel, Quickbird, and PlanetScope) - check the example gallery
Open Data Cube: Analysis toolkit of continental scale Earth Observation data from satellites. - seem to be a big machinery, could not find an easy use.
xarray-topo: xarray extension for topographic analysis and modelling. - dates from 2017, probably abandoned.
