SDI-Based Business Processes: A Territorial Analysis Web Information System in Spain

Spatial Data Infrastructures (SDIs) provide access to geospatial data and op-erations through interoperable Web services. These data and operations can be chained to set up specialized geospatial business processes, and these pro-cesses can give support to different applications. End users can benefit from these applications, while experts can integrate the Web services in their own business processes and developments. This paper presents an SDI-based ter-ritorial analysis Web information system for Spain, which gives access to land cover, topography and elevation data, as well as to a number of interoperable geospatial operations by means of a Web Processing Service (WPS). Several examples illustrate how different territorial analysis business processes are supported. The system has been established by the Spanish National SDI (Infraestructura de Datos Espaciales de España, IDEE) both as an experi-mental platform for geoscientists and geoinformation system developers, and as a mechanism to contribute to the Spanish citizens knowledge about their territory
