In January of this year, the project for setting up the new geoportal for the city of Koblenz was launched. The participants from the city administration, the Kommunales Gebietsrechenzentrum Koblenz, and terrestris have defined the milestones for the first half of 2018.
The application will first be put into operation in the intranet of the city administration and, in a next step, will be activated for citizens on the internet.
Technologically, the city of Koblenz relies on the following software components for implementation:
- SHOGun as a framework for providing the application
- OpenLayers and react-geo as client components
- GeoServer for the use of map and geometry services
- PostgreSQL / PostGIS as a database server
The overall system is based on SHOGun. The intended system is a classic client-server system. The client components are based on HTML5, JavaScript and CSS3. This ensures that it can be run without additional browser plugins.
Communication between the client components and the middleware (server backend) takes place via standardized web interfaces. Standardized OGC-OWS services, JSON or XML are used as communication formats.
At the conclusion of the project, the city of Koblenz will have a future-proof infrastructure at its disposal that meets the requirements of the administration and the citizens.
