Are DEMs specific for each country? I mean I got a preloaded DEM in my 3790T from the US, will that be applicable if I use it here in the Philippines?
Also, what does Basemap exactly show? In the tutorials, it says it shows the map of the world. Do I need it if I'm using my device here in the Philippines?
Please let me know. Thanks.
Aren't DEMs same as 3D maps because they seem to be in 3D right?
