Thanks for the suggestions. Well the area is Cape Verde, but Google earth image is pretty poor because the place is almost unheard of. Zoom in and its just a blur. Also there is no good DEM available without a dedicated survey so thats out.

So I just got go grayscale or build in Vue. I think you can export terrain map from Vue for Veg and maps, but I could be wrong..

Its a real pain. Ideally I need a zoomed in overhead view of the region to work from, but just can't find one anywhere...
