The cooperation of 5 companies directed by John Software GmbH Ilmenau made the fast production of a model showing the technology region Ilmenau possible. The model displays research institutions and neighbouring companies supplementing the large industrial plants at the Erfurter Kreuz area. In the first week of October 2011, the model (scale 1:1.000) was presented at the EXPO REAL in Munich. GTA generated a digital terrain model as well as the buildings from stereo aerial photography. The buildings were printed with a Z-printer (ULFTELLER 3DDRUCK), DTM and buildings were also used for a 3D PDF of the area (John Software GmbH).

Real models are very fashionable at the EXPO REAL in Munich. For the second time on behalf of the Landesentwicklungsgesellschaft, GTA produced in cooperation with ULFTELLER 3D DRUCK a model of an industrial area in Thuringia. GTA generated the 3D buildings from stereo aerial photography and designed the cartography for the model. The buildings and an aeroplane were printed with a Z-printer (scale 1:1.000).

In the second week of November the "Workshop 3D city models" is again taking place at the Uni-Club Bonn. The two day event is organised for the third time by the "Arbeitskreis 3D Stadtmodelle" of the two national cartography and photogrammetry and remote sensing organisations DGfK and DGFP.

Sven Baltrusch presents in his talk "Country-wide automatic and semi-automatic generation of 3D building models in Mecklenburg-Vorpommern" the approach of the Landesamt für Innere Verwaltung M-V, who uses the GTA software solution tridicon 3D.

You'll find program and registration form here.

GTA Geoinformatik GmbH presented its full range of new pathbreaking software solutions for automatic creation and utilization of 3D city models. tridicon^® 3D software automatically generates high-quality 3D buildings in LOD 2 from LiDAR point clouds, stereo aerial or satellite imagery.

Also presented was the off-the-shelf database Europe 3D which offers more than 180 European 3D city models at very competitive prices.

Virtual 3D goes real 3D - Three-dimensional multimedia model in Stade museum
(2011-06)

A large three-dimensional multimedia model is one of the new highlights of the exhibition on town history of Stade in Lower Saxony. On the ground floor of the museum Schwedenspeicher, which was reopened in May 2011 after a 8 months reconstruction period, the model leads in 6 episodes through the historic development of the town.

GTA measured a digital terrain model and 3D buildings using stereo aerial photography. For the outer parts of the town road infrastructure and watercourses were captured as a printable relief.

The model was printed with a Z-printer by ULFTELLER 3D DRUCK at a scale of 1:700. The media concept and production was realized by FrameGrabber Medien GmbH Hamburg, a projector overlays the model with additional information, three screens show different perspectives.

GTA is a member of the new network software initiative Neubrandenburg (SINB), which links software and IT companies in Neubrandenburg, and the counties Mecklenburg-Strelitz and Müritz.

SINB focusses on the following goals: to improve the successful realisation and coordination of cross-company projects, to promote young talent and to increase regional and national publicity of the participating companies. Since 2011 SINB is a member of IT initiative M-V.

A digital 3D city model can be visualized on a computer screen but using modern 3D printing technology, it is also possible to convert it into a physical model. For the 3D model of Unna GTA used stereo aerial photography to measure a digital terrain model and 3D buildings.

ULFTELLER 3D DRUCK marked listed buildings with a colour and printed the 3D city model with a Z-printer. The model has a scale of 1:500 and 25 tiles of A4 size.

The model was realized by Architektur Forum Unna e.V. with the financial help of sponsors and can be admired in the town hall of Unna.

tridicon^TM 3D uses stereo aerial imagery or LiDAR data to generate 3D city models

From March 1st until 5th at the CeBIT 2011 in Hannover, Germany, GTA Geoinformatik GmbH proudly presents its new software solution tridicon^TM 3D for the automatic generation of 3D city models.

In an automatic process tridiconTM 3D delivers high quality models in level of detail 2 (LOD 2) from stereo aerial imagery. Other suitable data sources are LiDAR data (airborne laserscanning) and stereo satellite imagery. Furthermore a digital terrain model and building footprints are used.

tridicon^TM 3D enables commercial users, municipalities and state offices to produce high quality 3D city models in LOD 2 fast, area-wide and cost-effectively.

Additional modules complete the software solution regarding data management, update and editing, analysis and visualisation of 3D city models.

On request data of interested companies or municipalities will be tested regarding their suitability.

Many thanks to Kempka & Scholz in Wismar for the brisk realisation.

Kathrin Hutton and Jan Tischer from GTA presenting tridicon 3D as a software for the automatic generation of 3D city models at the 5th international 3D GeoInfo Conference at the Technical University Universität in Berlin.  There was also a presentation of the cooperative project "Erfurter Kreuz" with the title Virtual 3D goes Real 3D.

Large areas suitable for industrial location are rare. Industrial and commercial park "Erfurter Kreuz" in Thuringia offers an excellent location in the middle of Europe that has still enough space even for large industrial plants.
To market this area successfully the Landesentwicklungsgesellschaft Thüringen (land developing association Thuringia) decided to attract potential investors at the EXPO REAL in Munich with a real (not virtual) 3D model.
In a project period of only two months cooperating companies GTA and ULFTELLER3DDRUCK completed flight mission, 3D modelling of relevant buildings, production of orthophotos and cartography. The buildings were printed on a Z-printer and assembled on tables with the aerial map. A nice eye-catcher! Read more (in German)

UFO or old ship? In any case the Müritzeum building in Waren (Müritz) which was opened in 2007 is an interesting piece of architecture that is worth a visit. Now this is possible in the internet with the help of Google Earth: on request of the Müriteum GTA made a virtual 3D model of the building. You can look at it from all sides: Have a look at Müritzeum.
Nevertheless it is worth a real visit as not only the building is interesting but also the exhibition inside.
