Drape DTM 2.0 gx


Does anyone know if the Oasis Airborne QC tool- 'Calculate Draped Survey Altitude' uses the Canadian Geological Survey's Drape DTM v.2.0 gx or algorithm? The CGS's doc for Drape DTM v.2.0 refers to drape_dtm.gx but I cannot find this gx.

Just wondering if it is the same tool as found in the Airborne QC extension.
