In the past year, the “GeoPortal Koblenz” went online as a new service of the eGovernment offering of the city of Koblenz. This web application is intended to be used as a citizen portal, for internal purposes and also as a future INSPIRE-compliant portal for the city’s geodata.

Thematic layers contain spatial information from various administrative areas in the urban area of Koblenz. This gives every citizen free access to selected official data. In addition, geo web services (WMS) of the state of Rhineland-Palatinate can also be integrated and displayed in the Koblenz Geoportal.

Do you want to know whether there are enough parking spaces at the CGM Arena Koblenz? Would you like to find out about the land value of a specific district? Do you want to travel to Koblenz and take a look around the city in advance? Or do you simply need the current version of the official city map of Koblenz? The new Geoportal of the city of Koblenz offers all this and much more.

The user can initially access four different map services: “City Map”, “Building and Living”, “Environment and Mobility” and “Land Values”. Within the map services, there are many different specialist topics: For example, in the “Building” topic, information symbols for the development plans are displayed with the corresponding scopes. When you click on one of the icons, further details are provided on an additional page. Electric charging stations, daycare centers or parking garages are also stored as “Points of Interest” (POI) in the map services.

Various maps are available as a background: the official city map (in various versions), aerial photos from the last 15 years, the WebAtlas Rhineland-Palatinate and the city base map. The expansion of the initially trilingual offering is on the agenda for the coming years. For example, construction sites, data from the municipal statistics office, information on municipal green spaces and 3D representations of selected locations could be integrated.

Technologically, the GeoPortal Koblenz relies on the Open Source WebGIS Framework SHOGun developed by terrestris. The OpenLayers and react-geo components used in the client lead to the implementation in responsive design, meaning that end users can use the application with a PC, tablet or smartphone.
