ABSTRACT: Incorporating Accumulated Geologic Knowledge in Computer Mapping

KUSHNIR, GRIGORY, GeoGraphix, Inc., Denver, CO

The complexity of geologic properties combined with irregular and scattered distribution of data points may produce geologically unrealistic features in computer-generated maps. The most common cases are mathematically induced anomalies in areas of sparse data distribution and at the edges of the mapped area (so-called edge effects), and improper dips between the clusters. In some cases a map does not even reflect geological concepts or hypotheses within the study area.

This paper presents the results of the surface substitution technique that incorporates accumulated geologic knowledge of sedimentation, structural development, geomorphology, trend surfaces, etc., in the process of computer mapping to increase geologic integrity of calculated maps (mathematical models). Real geologic data are used.
