Abstract: A distributed object-oriented geospatial database system and method thereof over the Internet using Web-based technology to perform data-driven queries, such as retrieving, viewing and updating, geospatial data of the object oriented geospatial database, such as vector, raster, hypertext and multimedia data, including data types or formats of ESRI shape files, GSF, oceanographic ASCII text data by NAVOCEANO and geospatial data with temporal information and supporting 3D display of the geospatial data. The object-oriented geospatial database system is implemented in a heterogeneous object-oriented development and integration environment through the Common Object Request Broker Architecture (CORBA).

Abstract: An object-oriented system for building and maintaining a spatial data structure for use in topological applications. The data is organized in a database which incorporates spatial feature location, attributes, and metadata information in a relational framework across a hierarchy. The system provides for the instantiation of the objects and levels that make up the database and for spatially indexing the data among the objects across hierarchical levels. The data can be updated while preserving the spatial linking among objects and levels, and the data can be exported to a relational vector product format database.
