Résumé(disponible en anglais seulement)
Through computer animations, we outline a prospective 3-D model construction method that builds on a 2.5-D geological mapping and data extraction technique based on vertical and oblique photogrammetry. We use an example from the Canadian Rocky Mountain thrust and fold belt, to demonstrate the method applicability in high relief areas. Photogrammetry-derived 2.5-D geological boundaries are more representative of geological elements than conventional 2-D maps and can be extrapolated to serial cross-sections to form the basis for 3-D model surface and volume constructions. The 3-D surfaces respect the constraints imposed by structural orientation data and the trace of key geologic planes such as folded stratigraphic contacts and faults.
