Within the framework of the XPlanung E-Government project, an object-oriented data exchange format, XPlanGML is being developed for loss-free exchanges among IT systems of zoning plans, regional plans, and land use plans, which supports internet-based availability of plans and allows evaluation and visualization of the contents of different plans.
This standardization opens up high potentials for making administrative procedures in the area of spatial planning more effective and less expensive, and improving their quality. Loss-free data exchange among various planning levels and different public and private organizations involved in planning in the course of the planning process is facilitated. At the same time, possibilities are opened up to make available planning-related data inexpensively to the business community (e.g. for regional business support or for location marketing), to other specialized authorities and public stakeholders as well as the public at large (public participation)
Since 2004, the XPlanung project has elaborated the specification of the XPlanGML data format, which meanwile is available in version 4.0.2. For supporting the implementation of XPlanGML, test data sets are available. Detailed information describing the strategic implementation of XPlanung, as well as a list of running and finished projects are found in the XPlanung-Wiki (in German).
Between January 2006 and March 2007, XPlanung was a model project of Geodateninfrastruktur Deutschland (GDI-DE) and, until 2006, a Media@Komm Transfer project. The Executive Board of the Deutscher Städtetag (German Association of Cities) recommended the introduction of the XPlanung standard. Moreover, the Urban Construction and Environment Committee of the Deutscher Städte- und Gemeindebund (DStGB) (German Association of Towns and Municipalities) at its meeting on April 21, 2008 recommended introduction of the XPlanung standard.
