ABSTRACT:
A terrain referenced navigation system utilizing a woods database model including a method for increasing terrain referenced navigation accuracy by compensating for the existence of deciduous forests. Deciduous forests present increased terrain referenced navigation inaccuracies during months that trees lack leaves. The terrain referenced navigation database is modified to include a woods bit to indicate the existence of a deciduous forest. The terrain referenced navigation algorithm is modified to account for the existence of the deciduous forest.
