+
+From the [Cartopy website](https://scitools.org.uk/cartopy/docs/latest):
+Cartopy is a Python package designed for geospatial data processing in order to produce maps and other geospatial data analyses.
+
+Cartopy makes use of the powerful PROJ.4, NumPy and Shapely libraries and includes a programmatic interface
+built on top of Matplotlib for the creation of publication quality maps.
+
+Key features of cartopy are its object-oriented [projection definitions](https://scitools.org.uk/cartopy/docs/latest/crs/projections.html#cartopy-projections), and its
+ability to transform points, lines, vectors, polygons and images between those projections.
