The AVL Thematic System is intended for the analysis-ready time series preparation. It integrates and uses commonly used toolboxes (such as, but not limited to, SNAP, Orfeo Toolbox, GDAL, etc.) into a single user environment. This framework allows for visual processing composition and execution distribution in such a way that end users could define by themselves workflows. It provides a rich EO dataset explorer that allows the querying and retrieval of EO data of different types (optical, radar, atmospheric, passive microwave, altimetric) from different providers: Scientific Data Hub, USGS Earth Explorer, NASA EarthData, Alaska Satellite Facility, CNES Theia, ESA FedEO and EOCat, LSA Data Center, AWS, for a various collection of sensors. Additionally, it directly supports EO data repositories from the DIAS platforms allowing the direct usage of the products (without download).
