Joseph:
Thanks for the additional tips.  Gmap4 is a very neat tool. Much gratitude to you for making it available.  In fact I think its already a large part of the utility of my Spot. Hard to understand how Spot can be promoted as a backcountry tool without real time connection to maps of better quality than Google Terrain.  Which I look at at as relief maps, not topos, and certainly not very useful for actual backcountry navigation.   So I have to ask, any chance of further development of Gmap4 to fill that void?  Real time projection of Spot data to MyTopo or similar quality?  Point and click/drag and drop file conversion of GPS data ?  I plan significant travel with some folks who would really like loved ones to be able to track them easily on decent maps.
Thanks again for your contribution
