Landmask (NaturalEarth)

The outline of the landmask is obtained from Natural Earth. It is automatically downloaded, cached¹ and opened with geopandas. The following landmasks are currently available:

• Land 1:110m
• Land 1:50m
• Land 1:10m

Note

If available, it is better to use the landmask of the used data set.

python

import matplotlib as mpl

# cut border when saving (for maps) mpl.rcParams["savefig.bbox"] = "tight"

Import regionmask:

python

import regionmask

Landmask

Warning

natural_earth_v4_1_0.land_50 and natural_earth_v5_0_0.land_50 do not extend all the way to 90°S (see #487). If Antarctica is of interest, please use natural_earth_v5_1_2.land_50 instead.

Be careful, however, as the regions may have changed between the natural_earth versions.

Note that land_10 and land_110 do not exhibit this problem.

python

land = regionmask.defined_regions.natural_earth_v5_0_0.land_110

@savefig plotting_landmask.png width=100% land.plot(add_label=False)
