actinia is a cloud-based geoprocessing platform with a REST API for analysing large volumes of geodata, including Earth observation data. mundialis GmbH & Co. KG has developed it since 2017, originally to process Copernicus data. The API integrates with GRASS GIS and GDAL and, according to the vendor, offers geo-analytical and remote-sensing methods, time-series analysis, satellite image processing and parallel computation in the cloud. It has a plug-in architecture and works with Jupyter notebooks. The vendor describes actinia as a SaaS solution and as open source.
mundialis is based in Bonn, Germany; its imprint names a German general partner and no foreign parent company. The source code is on GitHub under the GPL-3.0 licence and can be installed from PyPI or as a Docker image, so you can process geodata in your own environment. The hosting location of the SaaS variant is not stated; ask the vendor. This suits European organisations that want geodata analysis without depending on a US GIS platform such as Esri ArcGIS.
