3D-GEM: Geo-technical extension towards an integrated 3D information model for infrastructural development
Innovative model (3D-DEM) for semantic and geometric properties of geo-technical data. First model to reflect needs of users involved in infrastructural projects. The model can be easily integrated with above surface data via CityGML. The models provide links to other geological models GeoSciML and O&M.
