catchment_intersections
(gdir)[source]¶ 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: - gdir :
oggm.GlacierDirectory
where to write the data
Notes
- Files writen to the glacier directory:
- catchments_intersects.shp
- The intersections between cathments (shapefile) in the local map projection (Transverse Mercator).
- 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 (Transverse Mercator).
