Figure 1 - Schematic illustration of a line-of-sight calculation. A line is interpolated between two cells of the elevation model (left). If the heights of the intervening cells do not cross this line (top right) then there is a line of sight, if the height of any cell does exceed the height of the line (bottom right) then there is no line of sight.
