Abstract:

Northern Ireland, small and compact, geographically well defined with a relatively simple administrative structure, is able to establish a comprehensive Geographic Information System (GIS) that is one of the world's most advanced. The Ordnance Survey of Northern Ireland began the ten-year project to create the database by digitizing the current topographic archive, using a commercially available computer system. New data is being acquired through various types of remote sensing. All information is keyed to geographic coordinates, and the various users are responsible for supplying data and keeping it up to date, as well as establishing the needs and mechanisms for its use. The system operates within a VAX environment and eventually the database will hold 30 gigabytes of information.
