GAIA maps is doing an upgrade to their topo maps. Even free users can get the maps. It's in beta right now and they want beta testers.

I'm not real big into mapping so this is a nice upgrade for me. For hardcore mappers I guess maybe not. At any rate if you do like their stuff you might want to buy upgrades off their site and not the app stores as they give some nice discounts.

Here are some before and after screen shots and background info.

Just a PSA, I'm not associated with them in any way.
