Video #37
This video demonstrates the use of the Viewshed tool from the 3D Analyst extension - an ESRI addon that is additional cost.
Looking out from a single observation point, all the cells visible on a raster surface are used to create a new raster layer.
The result is either visible or non-visible surface.
In the next video (38), I show you how to turn that raster result into a polygon so it can be used for vector-based analysis e.g. what features are within the visible areas.
