Neat...I just wish there was an easy way to give the basemap library a 3-item tuple with (lat, lon, value) and have it automatically do a heat map and not just plot the points. That is an option in some software.

I have something of the sort. Give it later, lon and a value, it performs cubic interpolation and forms a heatmap. Some of the code is specific to my application but I'm sure you can reuse.

Thank you! I'll look.

basemap (like matplotlib) has the contourf method. You can calculate your x, y, and z values using matplotlib.mlab.griddata (altho scipy's are faster), and pass the results to it:

cartopy's website assumes that I know what I am doing.

There is no good entrypoint into the documentation, it just starts to tell me about projection details. The documentation outline is a list of the code functions with no clear point to start or indication which places might be good to start at.

I also can't find any examples for quick demonstration and trying. (edit: I found them after clicking all the links. Well... it's in the middle of a list of details I'm not interesting in and says 'Using cartopy with matplotlib'. Oh, at the bottom there is a link with more examples which I could find neither in the index nor in the outline... urgh.)

basemap's website also has a lot of problems, but it is a lot easier to use and we are lazy.
