Geospatial information sharing methods

A geospatial information sharing model was developed based on an abstract model of the information, a simple feature model, a geospatial relation model, a presentation method, and a geospatial reference system model. Two methods developed for geospatial information sharing on the Internet are the geospatial information markup language, GeoML, for geospatial information representation and the metadata management model for geospatial information management. Prototype systems were designed and implemented.EI0101405-14094
