hydromodpy.spatial.geographic.core.catchment_from_point

Delineate a catchment polygon from one outlet coordinate.

Purpose

Transform one configured outlet point into canonical watershed products (outlet.shp, outlet_snap.shp, watershed.tif, watershed.shp).

Pipeline position

Used when catch_def='from_outlet_coord' in the geographic workflow.

Processing steps

1. Build a point layer from x_outlet / y_outlet.

2. Snap the point to the nearest strong-flow cell on accumulation raster.

3. Run watershed delineation from D8 direction raster.

4. Polygonize the resulting watershed raster for downstream GIS/domain usage.
