oggm.tasks.glacier_masks

oggm.tasks.glacier_masks(gdir)

Makes a gridded mask of the glacier outlines.

Parameters:

gdir : oggm.GlacierDirectory

where to write the data

Returns:

Files writen to the glacier directory:

geometries.pkl

A dict containing the shapely.Polygons of a glacier. 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.

gridded_data.nc

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