[basemap] EASE grid projection

Hi,

I’d like to plot some EASE Grid global data (the EASE grid is defined for a cylindrical equal area projection). In proj4 parlance, it is defined as

+proj=cea +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +a=6371228 +b=6371228 +units=m +no_defs

My data are gridded, and I want to use either pcolormesh or imshow to plot them on a map. Apart from reprojecting into something that basemap deals with natively, is there something else that I can do within python/matplolib to plot the data without reprojecting it?

Thanks!

Jose

Jose: Shouldn’t be too hard to add support for that projection.
Could you file a feature request at
??

Jose: I went ahead and added support for the ‘cea’ projection to
pull request 73. You can get it by cloning my fork
