Problem
The README feature matrix is out of sync with the codebase. Broken file links, missing functions, and a few wrong backend-support markers.
Broken hydrology links
All hydrology functions moved to xrspatial/hydro/ but the README still links to top-level paths like xrspatial/flow_direction.py, xrspatial/watershed.py, etc. Every hydrology link in the feature matrix is broken (~20 links).
Missing functions
These public functions are exported from __init__.py but missing from the README feature matrix:
Hydrology:
fill (D8 sink filling)
sink (D8 sink detection)
flow_path (Dinf variant)
flow_path (MFD variant)
watershed (Dinf variant)
watershed (MFD variant)
hand (Dinf variant)
hand (MFD variant)
Classification:
binary (threshold-based binary classification)
Dasymetric:
validate_disaggregation (validates zone totals are preserved)
Wrong backend support markers
- Viewshed: Shows native CuPy (✅) but falls back to CPU unless RTX hardware is present. Should be 🔄 for CuPy and Dask+CuPy.
- Pycnophylactic: Shows blank for CuPy but works via CPU fallback. Should be 🔄.
Other
- Nav anchor bar missing a link to the GeoTIFF / COG I/O section.
- Intro paragraph says "100+ functions" but the library now has 150+.
