Some of my personal projects:
Includes isolines, isobands, direct raster values drawing and streamlines, barbs and vector images from vectorial fields.
Drawing choropleth maps is difficult in some countries when parts of them are far away from the mainland. This set of projections work like the original AlbersUSA projection, putting all the regions together.
Basemap is a great tool for creating maps using python in a simple way. It’s a matplotlib extension, so it has got all its features to create data visualizations, and adds the geographical projections and some datasets to be able to plot coast lines, countries, and so on directly from the library.
Basemap has got some documentation, but some things are a bit more difficult to find. I started this documentation to extend a little the original documentation and examples, but it grew a little, and now covers many of the basemap possibilities.
