Cartopy is a Python package harnessing the power of matplotlib to deliver informative, precise and striking maps.

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

Primarily the non-drawing functionality of cartopy makes use of proj.4, numpy, geos and shapely; with simple and intuitive interfacing to matplotlib for map drawing.

Some of the key features of cartopy are:

  • object oriented projection definitions
  • point, line, polygon and image transformations between projections
  • integration to expose advanced mapping in matplotlib with a simple and intuitive interface
  • work-in-progress mechanisms for accessing specialist data such as those from the “Shuttle - Radar Topography Mission” (SRTM) and the “Global Self-consistent, Hierarchical, High-resolution Shoreline” database (GSHHS).

Licensed under the GNU LGPL3, cartopy's latest documentation can be found at http://scitools.org.uk/cartopy/docs/latest and the source repository at https://github.com/SciTools/cartopy
