This is an awesome 3D image that attests to the DHS ability to determine the line of sight and distance based on elevation and environmental factors using GIS. I enjoyed using ArcScene to create this map. I encountered a problem with steps 10 & 12. I could not get the ortho image to appear on top of the elevation. I deleted the ortho layer and added it back a couple of times and it appeared as it should have. Not exactly sure what I did wrong or right for that matter, but it worked.
