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

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

The REST interface allows to access, manage and manipulate the GRASS GIS database via HTTP GET, PUT, POST and DELETE requests and to process raster, vector and time series data located in a persistent GRASS GIS database. Actinia allows the processing of cloud based data, for example all Landsat 4-8 scenes as well as all Sentinel-2 scenes in an ephemeral databases. The computational results of ephemeral processing are available via object storage as GeoTIFF files.

The full API documentation is available here: The source code is available here:
