I have just installed newer version of TA maps and they come with two DEM files. Should I use those or keep my one old low DEM file?
Thanx,
Bud

How many DEM files is enough?

You don't _need_ any DEM files. If you live in a particularly hilly area, larger DEM files will give you more 3D landscape look. Will use up more memory, too.

Thanx, Boris! I DO live in a hilly area and it is nice to see the graphical representation of the local landscape when navigating. I have, to my avail, three DEM files:
North_America_83_NASA_070919.dem (181K)
USA_83_CGIAR_081010.dem (118K)
NorthAmerica_low_2008_03_25.dem (181K)
So I guess they each in their own way are similar, correct?
I guess I'll pick one.
Thanx!

By the look of the file size, they are all pretty low-resolurtion, so you probably would not see much difference either way. The one I was using was about 254MB or so.
