JHS 188 Documentation and maintenance of the national road and street network information
The national legislation obligates the Finnish Transport Agency, National Land Survey of Finland and the municipalities of Finland to maintain a national road and street network information. The aim of this recommendation is to support the maintenance obligation of the before mentioned organisations and, as a result of the maintenance work accomplished with this recommendation and its instructions, to produce network information which is for content and structure predefined and which can be used and combined in different information systems more easily than today.
The recommendation handles the maintenance of national road and street network information with help of national link-node model and the information transfer based on the XML/GML schema (network topology schema) that was defined in the KRYSP project (project for electronic services for the built landscapes in the municipalities). This schema has been complemented with the obligatory parts from INSPIRE RoadTransportNetwork schema.
