Abstract
The purpose of this project is to create a geographic information system (GIS) that will allow researchers to record, analyze, manipulate and model geologic da a. The modelling process being undertaken here has a twofold purpose. The first is to recreate the interpretive capability provided by traditional methods. These traditional methods include the fence diagram, the isopach map and the conventional contour map. The second purpose is to incorporate additional analytical capacity with the traditional cartographic tools that will assist the visualization process as well as providing tools to quantify the observed phenomena. To accomplish these two goals, one must first examine how humans perceive their world and how these perceptions affect the efficacy of any modelling attempt. How humans use a system of logical inquiry to build up a practical and testable model of reality will affect the veracity and effectiveness of any modelling endeavour. The development of a GIS such as this requires the ability to collect, store and manage the data and information used, the ability to conduct robust analysis on these data, the preparation of cartographically sound representations of the analysis, and the capability to integrate the results of any analysis back into the database as the basis for additional study. Interpretation of the representations created will enable the researcher to integrate visually many factors that were previously difficult to assemble in one cogent form.
