Visualising Line-of-Sight Information in Matlab

There are many ways to visualize areas that are within line-of-sight of a sensor or communications transmitter. This document explains how to use combinations of commands from Matlab and the Matlab Mapping Toolbox to display line-of-sight information in maps. Line-of-sight information may be required for analysis in several areas relevant to Defense, including surveillance, reconnaissance, and communications. The techniques described here were developed for applications including radar siting and visibility from Unmanned Aerial Vehicles. The Matlab Mapping Toolbox includes routines to calculate line-of-sight based on terrain elevation data. The results can be displayed on two-dimensional and three-dimensional maps in various formats. This document describes how to use visualization and mapping commands in Matlab to produce a variety of line-of-sight maps to suit customers' requirements. The document gives examples of a range of display options that are possible in Matlab, and clear instructions on how to produce them. (11 figures).
