Basemap

Plot on map projections (with coastlines and political boundaries) using matplotlib.

Requirements

  • Python 2.6 (or higher)

  • matplotlib

  • numpy

  • pyproj

  • pyshp

  • The GEOS (Geometry Engine - Open Source) library (version 3.1.1 or higher).
    Source code is included in the geos-3.3.3 directory.

  • On Linux, if your Python was installed via a package management system, make
    sure the corresponding python-dev package is also installed. Otherwise, you
    may not have the Python header (Python.h), which is required to build Python
    C extensions.

Optional

  • OWSLib (optional) It is needed for
    the BaseMap.wmsimage function.

  • Pillow (optional) It is needed for
    Basemap warpimage, bluemarble, shadedrelief, and etop methods. PIL should
    work on Python 2.x. Pillow is a maintained fork of PIL.

Source code for the GEOS library is included in the geos-3.3.3 directory
under the terms given in LICENSE_geos.

The land-sea mask, coastline, lake, river and political boundary data are
extracted from datasets provided with the
Generic Mapping Tools (GMT) and are included
under the terms given in LICENSE_data.

Everything else (including src/_geos.c and src/_geos.pyx) is licensed under
the terms given in LICENSE:

problems or questions.

Install

  1. Install pre-requisite Python modules numpy and matplotlib.

  2. Then download basemap-X.Y.Z.tar.gz (approx 100 MB) from the
    GitHub Releases page,
    unpack and cd to basemap-X.Y.Z.

  3. Install the GEOS library. If you already have it on your system, just
    set the environment variable GEOS_DIR to point to the location of libgeos_c
    and geos_c.h (if libgeos_c is in /usr/local/lib and geos_c.h is in
    /usr/local/include, set GEOS_DIR to /usr/local). Then go to step (3).
    If you don't have it, you can build it from the source code included with
    basemap by following these steps:

     > cd geos-3.3.3
 > export GEOS_DIR=<where you want the libs and headers to go>
   A reasonable choice on a Unix-like system is /usr/local, or
   if you don't have permission to write there, your home directory.
 > ./configure --prefix=$GEOS_DIR
 > make; make install

  4. cd back to the top level basemap directory (basemap-X.Y.Z) and run
    the usual python setup.py install. Check your installation by running
    "from mpl_toolkits.basemap import Basemap" at the Python prompt.

  5. To test, cd to the examples directory and run python simpletest.py.
    To run all the examples (except those that have extra dependencies
    or require an internet connection), execute python run_all.py.

An alternative method is using pip:

pip install --user git+https://github.com/matplotlib/basemap.git
