actinia is an open source REST API for scalable, distributed, high performance processing of geographical data that mainly uses GRASS GIS for computational tasks.

It provides a REST API to process satellite imagery, time series, raster data with geographical relations and vector data.

The REST interface allows users to access, manage and manipulate the GRASS GIS database through HTTP GET, PUT, POST and DELETE requests. actinia can process data stored in persistent GRASS GIS databases as well as cloud-based data, such as Landsat and Sentinel-2 imagery, in ephemeral databases. Results from ephemeral processing can be exported as GeoTIFF files through object storage.
