OKGIS - Open Disastermanagement with free GIS-Components  

Die Projektpartner bearbeiten im Verbundprojekt folgende drei Schwerpunkte:

  • FH Mainz: Open Spatial Data Infrastructure (SDI), Web-Services and Web-Clients, Web Processing Services (WPS)
  • FH Oldenburg/Ostfriesland/Wilhelmshaven: Mobile geodata visualisation and creation
  • FH Osnabrück: Spatial support systems for coordinating offices


Main Focus FH Mainz

The main task will be to further develop the base components for realizing an open GIS conform geodata infrastructure (GDI), for disaster management purposes. These components need to be installed and integrated. Additionally, the data access components have to be accessible by the other project partners. Current OGC standardized processes (as well as other standardized organizations such as W3C and ISO) are incorporated during development and implementation of the GDI-server-components. As an OGC member we are using our obtained know-how to help optimize the already existing standards.
In order to have a client, which acts independent of the other projects, a web browser based client has been developed for testing server services. The main aspects which need further specification, implementation and integration are:

  • „Base GDI“: Development and extension of the spatial server components for a GDI based on degree2 frameworks.
  • „Alert Notification“: Development of an Alert Notification Mechanism for disaster situations.
  • „Sensor Incorporation“: Server side support for connecting sensors according to the OGC Sensor Web Enablement.
  • „Webclient“: Server based „Thin Client“- Solution for informing the affected population.


Main Focust FH Oldenburg

A mobile visualization and creation component based on SVG (Scalable Vector Graphics) is being developed for the GDI. The implementation is meant for mobile devices such as PDA´s or tablet pc´s. This way, attribute and geometry data can be requested, displayed and updated in the field. The viewer will also support the incorporation of sensor data. The following needs to be implemented:

  • The connection of OGC conform geo services
  • The integration of forms and creation elements with XML standard XForms
  • Returning the created information on and offline
  • Connection and integration of external servers


Main Focus FH Osnabrück

Geo based support system for decision making. In the coordination centers local applications access the GIS services and server components of the GDI. The obtained data is then processed and provides the base for automatic decision support systems. The support system should be installed in form of a „Rich Client“-System by coordination centers.
Characteristics and duties of the client:

  • Implementation of spatial and object related data from different data sources
  • Integrating up to date information coming from mobile relief workers on the scene, using mobile devices
  • Providing scenario specific and spatially clipped data, along with decision making suggestions for coordinators and relief workers in the field.
  • Decision support algorithms
  • Display of processed information in form of scenarios
  • Database for configured scenarios
  • Extension of already existing database and land register
  • Connection to other open standard interface disaster-management-systems
  • Mechanisms for documentation
