National Geographic Topo help

[LandCruiserPhil]

Can you turn off contours on National Geographic Topo, if so how? I have looked and looked - nothing I can find. Help

What version of nat geo topo? Nat geo support is surprisingly good. Have you tried contacting them?

Those are scanned maps vs something like DeLorme which is more of a database, so I don't believe you can manage layers as you would with something like an ArcView GIS tool.
