oggm.tasks.glacier_masks

oggm.tasks.glacier_masks(gdir, **kwargs)

Converts the glacier vector geometries to grids.

Parameters:

gdir : oggm.GlacierDirectory

Returns:

Files writen to the glacier directory:

geometries.pkl

A dict containing the shapely.Polygons of a divide. The “polygon_hr” entry contains the geometry transformed to the local grid in (i, j) coordinates, while the “polygon_pix” entry contains the geometries transformed into the coarse grid (the i, j elements are integers). The “polygon_area” entry contains the area of the polygon as computed by Shapely (it is needed because the divides will have their own area which is not obtained from the RGI file).

gridded_data.nc

A netcdf file containing several gridded data variables such as topography, the glacier masks and more (see the netCDF file metadata).
