ESA SNAP: sovereignty score and 8 European alternatives

SNAP, the Sentinel Application Platform, is a toolbox for processing and analysing Earth observation data, in particular imagery from the Sentinel satellites of the Copernicus programme. It provides a common architecture for the Sentinel toolboxes, a graph processing framework for building chains of processing steps, and tools for band arithmetic, reprojection and statistics over regions of interest. SNAP is offered as a desktop application that is installed and run on the user's own computer or infrastructure.

The European Space Agency (ESA) hosts the project on its STEP platform, and development is carried out with partners including Brockmann Consult in Germany and C-S in France. ESA is headquartered in Paris, and the source code is published on GitHub under the GNU General Public License version 3. Because SNAP runs locally and can be built from its public source code, European organisations can use it without sending satellite data to a cloud provider and keep control of the processing themselves.

Why digital sovereignty matters with ESA SNAP

ESA SNAP is headquartered in FR 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 ESA SNAP scores best on data residency.

ESA SNAP 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 ESA SNAP together with your other vendors and gives a total score, a heatmap and the main risk drivers.
