Development of 3D-GIS tools in 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 Gocad. },
