Line-of-Sight

This document describes how the TG Planner determines whether there is valid Line-of-Sight between two sites. We provide two approaches to modeling the propagation of radio waves to determine whether or not there is an obstruction: a simple cyclindrical model and a more accurate ellipsoidal model.
