I have had the program for a few years but I am still not a pro.
I flew an area and made a great model. Ultimately I imported the model into arcmap and made a topo base with 10' contours to use with my students while mapping.
The elevation range of the model is off and I want to recreate by manually adding elevation control points (either GPS points or use the published USGS quad to get benchmark elevations).
I feel like I have been through everything and can't even get "Markers" to appear.
How can I add 5 or six (or more?) manual elevation points to get more accurate topo lines?
