EDI BASED GEOGRAPHIC INFORMATION-SERVICE

EDI (Electronic Data Interchange) based geographic information service is a general client/server approach enabling automatic information service to end user applications. It is based on international standards and can be implemented with general EDI software tools. All important geographic data resources will be available for the applications which are able to send an electronic order through a data network and in real-time receive the response data sent by the data supplier's server system. EDI based information service is designed, piloted, standardised and implemented in Finland. Many of the national data suppliers are active and the service already covers ten databases. The Geographic Information Centre at the National Land Survey is maintaining a geographic data directory system and supporting the implementation of services and end user applications by consulting and by developing software supporting the standards.
