New Possibilities in Digitizing Aerial Images Enhance Safety and Usability of Valuable Archive Material (GTA 02-2012)
Most larger municipalities or government agencies as well as many privately owned companies from the geodata sector own a large archive of aerial imagery on film. These archives contain a value of many ten thousands of dollars which is hardly used or recognized. Today's scanning technology together with up to date software tools and data storage systems make possible a much higher scanning resolution than only few years ago. Where at that time a resolution of only 25µm produced far too much data to handle, now one can easily achieve a resolution of even 10µm without any issues. That means more than twice the resolution possible before. Read more

High-Quality 3D Modelling Using Georeferenced Photography
Production of georeferenced digital 3D landmarks from terrestrial photography using the software suite tridicon® 3D LANDMARK (GTA 01-2012)
For reasons of budget restrictions, the digital city models often are generated without any textures. However, the integration of sights like churches, museums, town halls and other important buildings as photorealistic 3D landmarks enhances a city model considerably and improves personal orientation as well as recognition value.

Tested in mass production and now new on the market: software for automatic production of 3D city models (GTA 2011-01)

The new software suite tridiconTM 3D delivers high quality models 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.
Depending on the type of source data and the targeted quality of the results different software suites are on offer. Applications like visualisation, quality control and editing of the produced data are integrated. One of the first customers of the complete software suite is the German „Landesamt für innere Verwaltung MV“ in Schwerin, which will produce 3D buildings for the federal state of Mecklenburg-Vorpommern country-wide.

Digitales Außenanlagenkataster spart Zeit und Geld (GTA 12-2010)

Interessant für Immobilien- und Wohnungsverwaltungsgesellschaften: Luftbildauswertung ermöglicht kostengünstige Erfassung eines Außenanlagenkatasters.
Fragen, wie „Wie groß sind die Flächen, von denen Schnee geräumt werden muss? Wie groß ist die Rasenfläche, die ich zur Pflege ausschreiben lassen muss? Wo genau steht der Baum, der gefällt werden soll? Wie lang ist der Zaun, der erneuert werden soll?“, stellen sich die Mitarbeiter von Wohnungs- und Immobilienverwaltungen sicher täglich. Idealerweise können sie diese Fragen ohne Vor-Ort-Begehung direkt im Büro beantworten. Dies wird ermöglicht durch ein digitales, GIS-gestütztes Außenanlagenkataster. (GIS = Geoinformationssystem)
Vorteile eines solchen Außenanlagenkatasters sind nicht nur der schnelle Überblick über die örtlichen Gegebenheiten, sondern auch die Abfrage von Informationen, wie Nutzungsart und Größe von Flächen, das Messen von Längen und Flächen direkt am Bildschirm und das einfache Einarbeiten von Korrekturen und Veränderungen. Das GIS ermöglicht den Zugriff auf die Daten durch verschiedene Bearbeiter und kann deshalb auch abteilungsübergreifend eingesetzt werden. (...) Diesen Artikel als PDF herunterladen.

Werkzeugkasten für 3D-Daten (Business Geomatics 11-2010)

GTA Geoinformatik bringt die Software, mit der sie seit Jahren erfolgreich 3D-Geodaten erstellt, nun auf den Markt.
(...) Die Erstellung von dreidimensionalen Stadtmodellen gehört besonders für größere Städte zum Standard. Doch häufig existieren nur sehr einfache Klötzchenmodelle des urbanen Raums. Ein Grund dafür liegt in den hohen Kosten, die die Erstellung genauerer Daten (meist aus Laserscanbefliegungen) oft mit sich bringen. Genau an dieser Stelle unterscheidet sich der Ansatz der GTA Geoinformatik. Die modular aufgebaute Software tridicon 3D verarbeitet - darin liegt ihr Alleinstellungsmerkmal - als Eingangsdaten georeferenzierte Luftbildpaare ebenso wie Schrägsichtluftbilder, LiDAR-Daten, terrestrische Aufnahmen oder Satellitendaten, aus denen 3D-Modelle generiert werden können. "Das ist im Vergleich der wesentlich kostengünstigere Ansatz", sagt Geschäftsführer Dr. Peter Lieckfeldt.(...)

Geoinformatik-Unternehmen unterstützt Kommunen bei der Einführung der geteilten Abwassergebühr (GTA 08-2010)

Luftbilder dienen als Grundlage für die gesplittete Abwassergebühr
Viele Kommunen stehen derzeit unter Druck, die erforderlichen Daten für die Einführung der gesplitteten Abwassergebühr zu erfassen. Aus Luftbildern kann die Flächenversiegelung ermittelt werden, was für die Festlegung der neuen gesplitteten Abwassergebühr maßgeblich ist. Künftig wird nicht nur die Frischwassermenge berechnet, sondern eine Schmutzwassergebühr und eine Niederschlagswassergebühr unterschieden. Dadurch soll eine gerechtere Berechnung der Gebühren erreicht werden.
Die GTA Geoinformatik GmbH führt Bildflüge durch und wertet zur Erfassung der Flächenversiegelung die aufgenommenen Luftbilder aus. Gestützt durch ein Geografisches Informationssystem (GIS) werden die erfassten Flächen digital oder in Form von Plänen an die Kommunen übergeben und bilden so eine Grundlage für die erforderlichen Berechnungen.
Aus den Luftbildern können außerdem Orthophotos, digitale Geländemodelle und 3D Stadtmodelle erstellt sowie eine Solarpotentialanalyse durchgeführt werden. Pressemitteilung als PDF herunterladen.

Geoinformatics company licences 150 European 3D city maps for navigation (GTA 05-2010)
GTA Geoinformatik GmbH (Germany) has delivered the first bundle of 150 European 3D city maps to customers dealing in navigation services. The 3D city maps are high-quality, detailed data in level of detail 2 (LOD 2) with generalised roof and wall textures and a very large coverage with an average of 30 sqkm per city. The 150 3D city maps were produced automatically from aerial imagery using the software tridiconTM ROOF which was developed by GTA. Several established producers of navigation software and devices already count on GTA’s 3D solution. GTA produces 3D city maps of 900 European cities which will be the basis for one of the largest commercial databases of 3D city maps worldwide. From now on the database “Europe 3D” is available for potential customers at advantageous conditions. Also planned and drafted is a database of 300 cities for the US market. The 3D city models are also suitable for other purposes than navigation and location based services like solar radiation analysis, urban planning, radiowave and noise propagation and others. GTA Geoinformatik GmbH has already compiled more than ten million buildings and produced more than 200 digital 3D city maps for European, North American and Asian capitals and major cities. Since the starting of 3D business, GTA has also produced more than 4.700 digital 3D landmarks. GTA, - founded in 1991 as geoinformatics company with ist main office in Neubrandenburg, is one of the leading producers in 3D production technology worldwide and has a staff of 50.

GTA Geoinformatik GmbH at the Intergeo 2009 in Karlsruhe (VDV Magazin 6-2009)
At the booth of GTA the most important topic was automatic roof modelling with tridiconTM ROOF, a software developed by GTA. Based on photogrammetric methods this technology offers an excellent cost-performance-ratio in the production of 3D city models.
Also presented was the camera system GeoSIS which was developed to take vertical and oblique imagery within the same flight misssion.
Using parts of a 3D city model of Munich different possibilities to texture roofs and facades were presented.
Great interest attracted the 3D city model of Berlin which covers with 892 sqkm the whole city in level of detail 2. Despite the large data volume the model can be visualised in realtime using the dynamic paging technology of the tridiconTM CityDiscoverer that makes data processing very fast. The software can therefore handle very large 3D models of any size.
Recent orthophotos of Berlin were produced in 2009 and can be purchased from GTA.
