USING KNOWLEDGE-BASE RULES TO MAP THE THREE-DIMENSIONAL NATURE OF GEOLOGICAL FEATURES

Accurate measurements of three-dimensional geological structural parameters, such as dip and strike measurements, can be extracted from remotely sensed imagery and digital elevation models. This involves finding edges in both data sets and, by using a least-squares approach, fitting a planar surface through the resulting three-dimensinal points. A knowledge-based system is required to assess the accuracy of the results and to combine the mass of structural data produced by these techniques into a realistic model of the geology.
