In the area of working with spatial data, in addition to the classic, two-dimensional geometrical data (maps, aerial
images, etc.), the needs for three-dimensional spatial data (city models, digital elevation models, etc.) is increasing.
Due to this increased demand the acquiring, storing and provision of 3D enabled spatial data in Geographic Information
Systems (GIS) is more and more important. Existing proprietary solutions quickly reaches their limits during data
exchange and data delivery to other systems. They generate a large workload, which will be very costly. However, it is
noticeable that these expenses and costs can generally be significantly reduced using standards. The aim of this research
is therefore to develop a concept in the field of three-dimensional spatial data that runs on existing standards whenever
possible. In this research, the military image analysts are the preferred user group of the system.
To achieve the objective of the widest possible use of standards in spatial 3D data, existing standards, proprietary
interfaces and standards under discussion have been analyzed. Since the here used GIS of the Fraunhofer IOSB is
already using and supporting OGC (Open Geospatial Consortium) and NATO-STANAG (NATO-Standardization
Agreement) standards for the most part of it, a special attention for possible use was laid on their standards.
The most promising standard is the OGC standard 3DPS (3D Portrayal Service) with its occurrences W3DS (Web 3D
Service) and WVS (Web View Service). A demo system was created, using a standardized workflow from the data
acquiring, storing and provision and showing the benefit of our approach.
