Our product
An open-source platform to access, process and visualize satellite imagery at scale.
Built for researchers, developers and organizations who want easier access to Earth Observation data.
In progress: AI-based object detection and segmentation (SAM, YOLO) on very high resolution imagery.
Our applications
Four demonstrators built in 2026 on the Earth Innovation Labs in Kenya: rainfall and drought, change detection, similarity search, object detection.
Each starts from the data of a STAC catalogue and ends with a web application with a map, charts and export. They can serve as the basis for a tool adapted to your data or your area.
Technical expertise
The tools we use every day, most of them open source.
Spatial databases, mapping applications and data catalogs.
