10 Years SIG 3D – 3D Geoinformation is long-lived

Date 2012.05.24

The Special Interest Group SIG3D has been in existence for 10 years now. It has generated exciting developments in the 3D sector, the new questions arising in the field of 3D information processing being not decreasing at all.

It all began in June 2002, in the run-up to the 2006 Football World Cup in Germany. The big cities on the Rhein and the Ruhr were to be jointly made visible as 3D images on the visitors’ PDAs, cell phones and touchscreens. The SIG3D was founded as a working group of the former Geospatial Data Infrastructure North Rhine-Westphalia (GDI-NRW) and works nowadays on a Germany-wide basis in the network of the GDI-DE (GeoData Infrastructure Germany).

In the years 2003/2004, 3D geodata of several cities and companies were for the first time exchanged, in the 3D Pilot 1 and 2, via transactional Web Feature Services and visualized through Web 3D Services on a screen display. Whereas at that time application scenes such as the fire run at the burning District Administration Center, visitor guidance to the World Cup stadium, commercial planning, and the interoperable 3D city models Berlin and Hamburg were the focus of this project, already as early as 2007 the whole territory of North Rhine-Westphalia was modelled in 3D for the purpose of the EC environmental noise mapping project. The specification of CityGML (City Geography Markup Language) was elaborated by the SIG3D as a 3D modelling and exchange format, adopted in 2008 as official standard of the Open Geospatial Consortium (OGC) and already developed further in its 2.0 Version of the OGC.

Since 2010 the SIG3D has been dealing with topics such as uniform quality and modelling regulations of 3D geodata, update of CityGML, introduction of ALKIS 3D, and merchantability of 3D geodata. The SIG3D has also managed to bring in parts of the CityGML standard into the setup of INSPIRE.

Many new challenges and issues will remain for the SIG3D to be dealt with in future, if one thinks in this context of catchphrases such as 3D portals in connection with Cloud Computing, Mobility and Social Networks.

The SIG3D is a both nationally and internationally independent working group of the GDI-DE dealing with questions concerning modelling, storage, compilation, usage, visualization, and marketing of 3D city and regional models. In particular the SIG3D encourages the setup of 3D Spatial Data Infrastructures with the aim of an improved availability and use of 3D geoinformation in all conceivable areas of application. Interested persons and parties are always very welcome.
