Question

When computing Line of Sight, how do we compute the altitude for an OPFAC w.r.t. the terrain profile and antenna height? What value do we use for the antenna height?

Answer

If the "Altitude is determined by Terrain" option is checked in the OPFAC/organization's attribute dialog box, then the software uses the terrain information and 2.5 m for the antenna height to calculate the altitude of the OPFAC. If disabled, it just uses the value specified in the altitude field for its LOS calculations.
