....database servers through JDBC and OpenGIS for SQL. The OpenGIS for SQL specification defines a standard SQL schema that supports storage, retrieval, query, and update of geospatial feature collections via the ODBC or JDBC API. Currently, OpenGIS Simple Features Specification for SQL is available [19]. Among the commercial products that conform to this specification are Oracle Spatial Option [23] and ESRI Spatial Database Engine (SDE) 7] 4. System architecture Figure 3 depicts our architecture for building open and interoperable GISs. It is a CORBA based implementation of the abstract ....
....of the prototype implementation. Detail description of its components follows next. 5. 1 Server side implementation In the current implementation, GIS data are retrieved from Oracle databases with Oracle Spatial Option [23] that conforms to OpenGIS Simple Features Specification for SQL [19]. According to the SQL schema defined in the specification, each GIS layer is stored as a feature table. Each feature is stored as a row in the table. The non spatial attributes of a feature are mapped into columns whose types are drawn from the set of standard SQL92 data types. The spatial ....

....it is hard to estimate the position of the target data on the WWW, the search sequence of the query in either language is described using a regular path expression. 2.2. Geographical Relational Openators Geographical relational operators have been standardized by the Open GIS Consortium, Inc. [12]. The consortium has proposed geographical models of 2D or 3D objects, relational operators among objects, and SQL for database operations. The objects include classified attributes such as positions, shapes, addresses, and owners. The relational operators enable us to evaluate object relations ....
....a query language for the above augmented Web space, based on the query languages available for Web space search. Here, because geographical relations on HPs are basically independent of the WWW hyperlink network, and are not defined as HTML tags, we use geographical operators defined by Open GIS [12]. Figure 3 shows an example of a generic link that is obtained by applying GIS geographical operators to HPs. To search the augmented Web space, we use extended regular expressions in order to handle the semi structured Web space. These path expressions specify sequences of HPs and hyper generic ....
