Sample Line of Sight (LOS) imposed on the DEM layer at Memorial Stadium shows the topography and obstructed areas (red) for viewing the stadium for security. I had to change the transparency from 60% to 80% to get a clearer image of the LOS lines. The V shaped LOS is from a tower that would provide a security observation point overlooking the tennis courts and associated parking lot.
I had trouble with this as I copied the LOS lines into the DEM layer. Some LOS were not intersecting the perimeter of the stadium. I could select some LOS for copy, but the did not paste into the image. When I turned off the orthoimage layer, they were not even under it to "move to the top".
