Masterportal is an open source geoviewer (WebGIS) compliant to OGC standards. It is highly configurable and is based on a configurative approach – it needs no programming knowledge to set up. Requirements are limited to a simple webserver and the availability of OGC-services. With numerous OGC interfaces available and many ready-to-go tools, the Masterportal offers the possibility of setting up a WebGIS within minutes.



The Masterportal is developed in JavaScript, CSS and HTML and is based on several other robust OpenSource libraries such as OpenLayers, VueJS, Bootstrap 5 or ChartJS. It is published under MIT License and is thus available to be used in any context.

The Masterportal was originally designed by the city of Hamburg based on the needs of a smart municipality and is now being further developed by a large developer community.
