Forcing GM to use the highest resolution terrain data layer

Sorry, me again.

I am using SRTM and similar data for wide area terrain analysis but then want to use higher resolution data in specified small areas in order to get greater accuracy for Line of Sight and ViewShed analysis. If I have loaded several layers, all of different resolution in different areas, can I get the ViewShed and Line of Sight tools to use whatever the highest resolution data is for each area, and if so, how?

    That happens automatically. Just load your lower resolution data first, then the higher resolution data. Global Mapper automatically uses the top-most layer at each location. You can re-order after loading by moving layers in the Control Center.
