In TNP 11.x, The current best “merged SAR view” that is not too dark (viewing or printing), and that you can still see most all the topo lines is: Select “topo”, then merged with the “Aerial Ortho Enhanced”……………..all the topo lines are still visible, and the sat view is the lightest………………………..All the other combos give a very dark image merge with most topo lines unable to really be seen.In all cases using Sartopo or Mission Manager, I find I always lighten the sat/aerial view to see the topo better, but at the same time can see the open spaces/buildings….. So in the future if you give a single option that dims the sat/aerial view say 50% in merge giving the topo view the predominate I think that would do it.
