First Experiences with GEOSTORE , an Information

Since the beginning of 1993 our group is a member of the SFB \Interactions of Continental Substance-Systems and their Model-ling" 1. In this interdisciplinary project about 20 groups of the University of Bonn, mainly geoscientists, are participating. To provide the SFB with database technology as soon as possible, we decided to develop GEO-STORE, a rst prototype system which is restricted on the management of geologically deened geometries such as 3D-points and triangulated 3D-surfaces of geological layers and faults. The functionality of GEOSTORE includes the management of three dimensional geological surfaces, the checking of spatial integrity constraints, the 2D-visualization of the ex-aminated area in the Lower Rhine Embayment and a 2D-visualization of horizontal and vertical intersections with 3D-faces. GEOSTORE has rst been realized on top of a relational DBMS and secondly on top of an ODBMS. For the 3D-visualization of the geological layers and faults a coupling with GEOCON, a 3D-construction and modelling tool for geological surfaces, is realized via remote procedure call.
