oggm.tasks.catchment_intersections

oggm.tasks.catchment_intersections(gdir)

Computes the intersections between the catchments.

A glacier usually consists of several flowlines and each flowline has a distinct catchment area. This function calculates the intersections between these areas.

Parameters:

gdiroggm.GlacierDirectory

where to write the data

Notes

Files written to the glacier directory:

catchments_intersects.shp

The intersections between catchments (shapefile) in the local map projection.

flowline_catchments.shp

Each flowline has a catchment area computed from flow routing algorithms: this shapefile stores the catchment outlines (in the local map projection).
