Inframodel Data Exhange

Inframodel is an open method for the exchange of infrastructure information. It is based on the LandXML-standard. The initial version is Inframodel3, which includes parts for terrain models, subsoil surfaces, road and rail geometries and construction layers. It also covers water sewage and supply and some facilities.

Inframodel documentation explains the Finnish method for using LandXML. Inframodel does not gather all the elements in LandXML. On the other hand some Inframodel specific extensions have been added. The most important of these is the Infra classification system.

Inframodel is the exchange format required by the Finnish Traffic Agency and major cities since May 1st 2014.
