DeriveAirspaceGeometry

Summary

Creates geometry for derived features.

Discussion

The Import AIXM 4.5 to AIS tool will create a null geometry for an airspace feature if AIXM messages contain instructions to generate derived airspace geometries. This function updates the null geometry with a polygon derived from other airspace features.
