Communities

Innovation via Cooperation - a one world GI competence network

52°North’s collaborative software development process is organized in so-called R&D Communities. Each community focuses on a particular/common R&D topic which is driven by partners’ interests. The communities are:

  • 3D aims to create applications and services which visualize 3 dimensional geo-objects and establishing a creative surrounding, which allows efficient and sustainable development of innovative software solutions in the context of 3d modeling and 3d geovisualization.
  • Earth Observation promotes the use of free near real-time environmental and Earth Observation data and derived products to a worldwide user community.
  • Geoprocessing aims to provide ready-to-use standardized web-geoprocessing software, as well as, prototype implementations to enable processing of geo-data in Spatial Data Infrastructures.
  • Geostatistics focuses on development of software for modeling, analysis and visualization of spatio-temporal data, error propagation modeling and uncertainties.
  • ILWIS continuously develops Integrated Land and Water Information System (ILWIS), a remote sensing and GIS software into re-usable, interoperable web services.
  • Metadata Management aims to evaluate new techniques for collecting, managing and retrieving metadata as to advance the existing methods and tools.
  • Security and GeoRM focuses on security, rights and access control in geospatial services, providing ready-to-use software as well as prototype implementations to enable business and access control process for SDI.
  • Semantics aims to provide a Semantic Enablement Layer (SEL) for services developed within the 52°North communities to support semantics-based information systems.
  • Sensor Web focuses on the development of a broad range of services and encoding implementations related to Sensor Web research.

Communities are set up and terminated by 52°North's Executive Board in consent with the Advisory Board. Within each community, a community leader (CL) manages and coordinates the software development process, i.e. he steers the development according to the community’s vision/mission, creates a road map in which mile stones are identified and helps to identify pioneering concepts. He also facilitates Community activities to foster effective collaboration and tangible benefits for the participating institutions and individuals. The Executive Board appoints a Community Leader for each Community. Software quality assurance is carried out by a code quality manager. He is appointed by the CL.

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.

Metadata is an essential means for providing access to spatial data and spatial information services. Accordingly metadata is one of the main building blocks of Spatial Data Infrastructures. Today the standards from ISO and OGC are representing the state of the art in metadata management. But both requirements and technologies are evolving continuously.

The Metadata Management Community aims at evaluating new techniques for collecting, managing and retrieving metadata as to advance the existing methods and tools.
