The cartopy Feature interface#
The data copyright, license and attribution can be blended on the map using text annotations (mpl docs) as shown in feature_creation.
Specific Feature subclasses have been defined for common functionality, such as accessing Natural Earth or GSHHS shapefiles. A list of these can be found in the reference documentation.
To simplify some very common cases, some pre-defined Features exist as cartopy.feature
constants. The pre-defined Features are all small-scale (1:110m)
Natural Earth datasets, and can be added with methods
such as GeoAxes.add_feature:
Name  | 
Description  | 
|---|---|
  | 
Country boundaries.  | 
  | 
Coastline, including major islands.  | 
  | 
Natural and artificial lakes.  | 
  | 
Land polygons, including major islands.  | 
  | 
Ocean polygons.  | 
  | 
Single-line drainages, including lake centerlines.  | 
  | 
Internal, first-order administrative boundaries (limited to the
United States at this scale).
Natural Earth have first-order admin boundaries for most
countries at the 1:10,000,000 scale; these may be
accessed with   | 
Note
Any Natural Earth dataset can be used by creating an
instance of cartopy.feature.NaturalEarthFeature. For
example:
import cartopy.feature as cfeature
land_50m = cfeature.NaturalEarthFeature('physical', 'land', '50m',
                                        edgecolor='face',
                                        facecolor=cfeature.COLORS['land'])
A dictionary of some useful colors for drawing features also exists in cartopy.feature.COLORS.
For a full list of names in this dictionary:
>>> import cartopy.feature
>>> sorted(cartopy.feature.COLORS.keys())
['land', 'land_alt1', 'water']
