Internet/ Intranet What do we need? central stored data (middleware software & database) have access to geoobjects for viewing and manipulating using open standards store objects and their properties communicate with geomodel (like conventional 2d GIS) 03/28/11 Text in der Fusszeile 6 6

Web Feature Service (WFS) webservice: describe, get, modify geodata Geography Markup Language (GML) XML definition of geometries Geoscience Markup Language (GeoSciML) Property model for geoscience data Simple Feature Standard (SFS) Defines data structures for storing geodata in DBMS Implemented in PostGIS 03/28/11 Text in der Fusszeile 7 7

On database side... Extension to PostgreSQL DBMS (similar to PostGIS) our system is called PostGST (geospatial and temporal) class based model design define classes of geoobjects connect properties to geoobjects On Vertex level (eg. on point) On Simplex level (eg. on tetrahedron) 03/28/11 Text in der Fusszeile 9 9
