terrestris: sovereignty score and 8 European alternatives

terrestris is a German company that describes itself as an open source specialist for maps and spatial information systems. It provides consulting, concept and architecture, software development, project management, quality and test management, operation and maintenance, and training. It works with open source components such as GeoServer, OpenLayers, MapProxy, PostgreSQL with PostGIS, GeoStyler and Masterportal. One of its own projects is SHOGun, a Java framework built on Spring Boot for the backends of web applications in spatial data infrastructures, with secured REST and GraphQL interfaces. terrestris also offers OSM WMS services in a free and a premium version. Its solutions are delivered as professional services and as software that customers run themselves.

terrestris GmbH & Co. KG is headquartered in Bonn, Germany. Its software is open source and published on GitHub, with SHOGun licensed under Apache-2.0. An organisation can therefore host and operate the components itself, or hand operations to terrestris; the website does not describe where such operations take place. The sources mention no foreign parent company.

Why digital sovereignty matters with terrestris

terrestris is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so terrestris scores best on data residency.

terrestris is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs terrestris together with your other vendors and gives a total score, a heatmap and the main risk drivers.
