# 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`]:
```sh
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`]:
```sh
python -m pip install basemap-data-hires
```
This package depends optionally on [`OWSLib`] for the `Basemap` method
`Basemap.wmsimage`.
## License
The library is licensed under the terms of the [MIT] license (see
[`LICENSE`]). The GEOS dynamic library bundled with the package wheels
is provided under the terms of the [LGPL-2.1-only] license as given in
[`LICENSE.geos`].
## Documentation
See https://matplotlib.org/basemap/.
See scripts in the `doc/examples` directory for example usage.
Read the FAQ and/or email the matplotlib-users mailing list if you have
problems or questions.

## 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).
