Guide for working with geography with spring data Geo

[xenoterracide]

I'm finding the concept of working with geography a little hard from googleing. I really wasn't able to find much documentation on the Geo support either. It's kind of a footnote in spring data commons. I'd love to see a guide that gives an example of working with some kind of map data. I'm personally using neo4j but if JPA (postgis), or MongoDB is preferred, or even something else, I'd be okay with that.
