matplotlib/basemap

basemap

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

Installation

Precompiled binary wheels for Windows, GNU/Linux and MacOS are available on PyPI and can be installed with pip:

python -m pip install basemap

For specific details on how to install basemap through conda or from source, please refer to the basemap installation instructions in the documentation.

Requirements

This package depends on basemap-data with the basic basemap data assets supporting the essential functionality.

This package depends optionally on basemap-data-hires with the high-resolution data assets, which can be installed manually with pip:

python -m pip install basemap-data-hires

This package depends optionally on OWSLib for the Basemap method Basemap.wmsimage.

Known bugs

The Basemap.fillcontinents method doesn't always do the right thing. Matplotlib always tries to fill the inside of a polygon. Under certain situations, what is the inside of a coastline polygon can be ambiguous, and the outside may be filled instead of the inside. A workaround is to change the map projection region slightly or mask the land areas with the Basemap.drawlsmask method instead of filling the coastline polygons (this is illustrated in the ortho_demo.py example).
