Offline DEM data/map
I would like to use off line altitude data like in Garmin GPS. Here I can use open source DEM map wich is give information for other maps. So I can see alt under cursor or I can use alt date for profile. Or I can use topo map with DEM info and other maps are use them too even this map isn`t active.
So: off line DEM data maybe would be nice too for track calculated inside locus or even for those computed in the cloud off line DEM date stored on SD card could be used insted of fill in altitude option.
