I got a Lowrance GPS (ifinder H2o) for Christmas. Can anyone recommend a map company that supplies downloadable lake maps for the state of georgia. Thanks Chris
This website has about all the map info you need! I don't know if it suits your GPS unit or not. If not, perhaps it can be ran thru a script if the GPS unit only requires text based documents (ie csv docs).
I've been using the Google Maps API and the ability to export data directly to Google Earth. I don't know if that would help at all. I know that their forum (dare I say) has a lot of GPS lists.
