The GML toolbox primarily supports the XPlanGML standard. It is a simple tool for generating XPlanGML models from existing plan information, for reading and writing XPlanGML data records and for visualizing XPlanGML with SVG vector graphics. The software is also able to check XPlanGML documents geometrically and semantically (schema validity, conformity conditions).
Besides XPlanGML, the GML toolbox supports the standards CityGML (basic standard and ADEs), BoreholeML, ALKIS/NAS as well as the INSPIRE data format INSPIRE-PLU. In addition to reading, writing and visualization (for 3D data via the KML format and the GoogleEarth viewer), geometric inspection is also possible for these data formats.
