I am looking for the optimal location to place a radio repeater on a 25,000 acre preserve. Therefore, I need to determine a point with the largest viewshed of the property that is within a 1/4-mile buffer of a hiking trail or road.I have layers for the preserve boundaries, DEM, trails/roads, and a 1/4-mile buffer all laid out, but I am unsure how to proceed. I know there are viewshed and observer point tools, but I am not certain how to use them to my desired end.
