OKGIS - Open Disastermanagement with free GIS-Components  

The overall goal of the project OK-GIS is the development and implementation of an open concept for the administration, usage, visualization and mobile acquisition of geographic information. This will be based on open standards set by the Open Geospatial Consortium (OGC) for web-based GI services. The free software components being developed by each of the project partners will be joined to a prototypical disaster management system. This will show the potential of such a system even on heterogeneous devices (mobile or desktop-PC).
The overall architecture is generic and can be adapted to several types of natural or man-made disasters, but we will focus on several scenarios and use cases. For example flood waters and fires will be used as exemplary scenarios within this project. This will be done in cooperation with the fire brigade in Osnabrück and the public utility company (Stadtwerke) Osnabrück. These institutions will help to make the system usable corresponding to the requirements in Germany. Additionally the persons in charge of the EU-project MILES who support the technical reconstructions in Sri Lanca, have agreed to bring in their experiences. This includes the requirements in developing countries, especially in South-East-Asia with a focus on deluges.
The project is being implemented by three reserch partners: The " Institut für Angewandte Photogrammetrie und Geoinformatik " (IAPG) at the University of Applied Sciences Oldenburg/Ostfriesland/Wilhelmshaven, the University of Applied Sciences Osnabrück and finally the Institute for spatial Information and Surveying - i3mainz . At the University of Applied Sciences Mainz, with Prof. Alexander Zipf, as the overall project lead. Further partners include several GI companies (see below).

Currently, a bomb threat scenario is an additional scenario as an example of a man-made disaster. Here a danger zone is derived by buffering the bomb find area by a certain amount of meters. Adding building type information such as schools, kindergardens etc. and intersecting them with the danger zone, can help prioritize evacuation resp. search and rescue. By including an emergency route service, relief workers can assign avoid areas, which the service will incorporate into its calculation, providing by pass directions for faster and safer access.
The processes for this scenario (calculation of threatened areas, emergency route calculation, avoid areas, etc.) are transferable to different emergency related scenarios and requirements.
