A gentle introduction to actinia: geoprocessing in the cloud
Markus Neteler, Carmen Tawalika

Actinia ( is an open source REST API for scalable, distributed, high performance processing of geographical data that mainly uses GRASS GIS for computational tasks. Core functionality includes the processing of satellite imagery (both single scenes and time series), as well as the processing of raster and vector data, even from external sources. The existing big Earth observation open data pools (Landsat, Sentinel, etc.) are growing day by day along with a plethora of other sources. Actinia is designed to follow the paradigm of bringing algorithms to the data, saving users from locally downloading and processing huge amounts of data. Actinia is an OSGeo Community Project since 2019. It can be deployed with docker-swarm on a workstation, and also in OpenShift and kubernetes.

In this workshop we will give a short introduction to REST API concepts and some cloud processing background. This is followed by an introduction to actinia processing along with hands-on to get more familiar with the topic by means of exercises (from terrain analysis to QGIS visualization; from aerial image to classification with vector export; controlling actinia from a GRASS GIS session). This workshop is geared towards those with basic experience in geospatial analysis. And we are looking forward to enlarge the actinia community!
