This follows on from last week. This time we had to use the elevation data and create lines of sight from the NORAD tunnel entrance at Cheyenne Mountain, Colorado for people protecting the entrance. It was quite interesting to see this work, although my 4th deliverable, supposed to have been created in ArcScene (the 3D view), only would work in 2D as a jpeg and I'm not even sure I got it to work correctly.
However, in 2D, here are a couple of images: the grey one with the red-and-green lines shows an aerial view of the NORAD tunnel entrance with lines of sight (green = visible, red = impeded). The other one is a conventional map view with a 3-mile buffer round the NORAD site and a 500-foot buffer round the nearest airport, or rather, heliport.
