The semantics community is in the making! It focuses on providing a Semantic Enablement Layer (SEL) for services developed within the 52° North communities to support semantics-based information retrieval, discovery, on-the-fly integration, semantic translation, as well as further reasoning services.

This emerging community focusses on the modelling and statistical analysis of spatio-temporal data, and on the quantitative expression and visualisation of data accuracy, control of data quality, and error propagation.

We develop software for the modelling and statistical analysis of geospatial and spatio-temporal data. We do this by connecting the 52°North Sensor Web and Geoprocessing communities with analysis and modelling communities, including the community involved in the open source statistical computing environment R, and e.g. atmospheric dispersion modelling communities. One of our immediate goals is to interface the comprehensive statistical functionality of the popular open source R environment to the geospatial user world through open standards, such as those endorsed by the OGC.

A strong partner of the geostatistics community is the spatio-temporal modelling lab at the Institute for Geoinformatics (ifgi) of the University of Muenster. The researchers of this group contribute their public work to the 52°North open source initiative to ensure a wide distribution of their work, and to benefit from the partner network and dissemination activities.

The 3D Community focuses on creating applications and services which visualize 3 dimensional geo-objects using the software framework Triturus (pronounced "tritoorus").

The community's vision is to establish a creative surrounding, which allows efficient and sustainable development of innovative software solutions in the context of 3d modeling and 3d geovisualization.

The scope of Triturus may be terrain modeling, landscape planning, civil engineering or sensor web – just to mention some examples. Any other field dealing with geo-information visualized using three geometrical coordinate-axes (x, y, and z) is within the project's scope.

Development goals are:

  • to provide a surrounding for 3D geovisualization tasks, broadly usable in different fields
  • to have open ended software that is easily extensible
  • to be compatible to existing standards in the context of geo object modeling and computer graphics (OGC, ISO, W3C).


Characteristics of the framework:

  • Development platform: Java (Windows and linux/unix)
  • Rendering pipeline (filter, mapper, renderer) as the reference model
  • Abstraction of concrete (geo-)datasources and renderers through interfaces
  • Integration of basic I/O-classes and renderers (3d realtime rendering and ray tracing)
  • Freely available implementation examples using this framework: Web Terrain Service (OGC-WTS for LOD 0), profile service for the generation of terrain cross sections, web application for WTS visualization using OGC-WMS as drape texture.

A White paper is available which explains the basic concepts underlying the framework, as well as the underlying design philosophy. Moreover, it describes the first applications built on top of the framework.
