I'm working on a final project for a class. I'm trying to preform a viewshed from two separate cellphone towers over a large mosaic of DEMs. I have basically extracted the values from the DEM (with the height of the towers) and applied them to the tower point
shapefiles. When I preform the viewshed I get very poor visibility results which I wasn't really expecting could anyone provide some
insight about what I am doing wrong or what I should be doing?
