EnviCat can be used for documentation of geodata with ISO metadata in a distributed environment. Input of metadata is done in batch mode or with Java forms. An ActiveX-based GUI similar to Windows Explorer is developed for integrated WWW-based browse/query and visualization of metadata and geodata. Data can be ordered and downloaded online. Before download, automatic processing can be ordered (clipping, feature extraction, and format and projection conversion). The system can handle multiple user groups with complex access rules. All data can also be visualized with ArcView IMS. Key components are SDE, Oracle, Oracle Web application server, ArcView IMS, ISO metadata, VB ActiveX, and FME. Among the customers are Intranets for the Swedish Road Authority, the Swedish Space Corporation, the Swedish National Land Survey, the Swedish EPA, and the European Environment Agency.
