Greg kindly posted a comment to my earlier post on the CIESIN poverty maps, to let me know that CIESIN is making GE versions of its data via WMS. I’m promoting it to a post. I’ve made a network link to view some of his files here; the resolution of the images increases as one zooms in.
The global and national shapefiles themselves are of course a useful research resource. To access other great CIESIN datasets, click here.
