Cartopy is a Python package designed to make drawing maps for data analysis and visualisation as easy as possible.

Cartopy makes use of the powerful PROJ.4, numpy and shapely libraries and has a simple and intuitive drawing interface to matplotlib for creating publication quality maps.

Some of the key features of cartopy are:

  • object oriented projection definitions
  • point, line, vector, polygon and image transformations between projections
  • integration to expose advanced mapping in matplotlib with a simple and intuitive interface
  • powerful vector data handling by integrating shapefile reading with Shapely capabilities
