Development of a 3D GIS based on the 3D modeller Gocad

Abstract

Large-scale mineral exploration studies or regional mapping campaigns often result in large and complex spatial models consisting of many geological objects. For those models it becomes difficult to determine the spatial, temporal, and structural relationships between the modelled geological objects and their consistency. This task requires tools for querying the model for those relationships, and methods to represent the query result graphical or using meta-data. So far, a set of topological and directional query tools, and a legend have been implemented as a prototype version in the Gocad 3D modeller.
