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).
