Computing aspects of a large geographic information system for the European Community
نویسندگان
چکیده
The CORINE programme has now been underway since 1985. Its purpose is to provide information on the environment of the entire European Community in a form suitable for assisting policy-making. Such data must be accurate, integrated and readily available to the personnel for whom it is designed. The system must be capable of dealing with large amounts of spatially linked data from many different data sources, in text, vector or raster form. Therefore the use of a Geographic Information System (CIS) is essential. This paper describes the use of an interim system as a 'test bed' for beginning the process of data acquisition and integration. The data sets available are soils, climate, topography and 'biotopes' important areas for nature conservation. A data transfer format has been devised to provide for ease of transfer between various EC sites working on different mainframe computers. The interim system ensures that user needs can be defined and provides valuable user experience before a permanent system is installed. Other issues examined include the use of national and international networks and problems of data integration when incorporating existing digital data from disparate sources into a large CIS.
