I've been reading the tutorials and discussions here about loading custom maps on my GPS and I'm very excited about the possibilities. I downloaded the California topo file and loaded a portion of it on my eTrex Vista Hcx, and I am underwhelmed by the lack of detail on the map. I was hoping for a richer image, similar to what I have in TOPO!
I am planning a hiking trip to France for this fall, so I have been researching downloadable maps for the French Alps. IGN has the best 1:25,000 maps, and they even have a software program comparable to TOPO!. But, it won't transfer images, only points and tracks. I found a program at SourceForge called
TopoMap, which downloads img tiles from IGN, or the equivalent servers in Spain and Germany.
In reading the tutorials here for installing img files in MapSource, the section for those of us with img tiles but no tbd file, the author references a txt file as a stand-in for the tbd file. I couldn't find any reference for what this txt file contains, or how to create one. I'm anticipating having upwards of 1,000 img files to compile, with no way to arrange them.
Any help here?
