The Austrian Semantic EO Data Cube Infrastructure

Martin Sudmanns, Hannah Augustin, Lucas van der Meer, Andrea Baraldi, Dirk Tiede
2021 Remote Sensing  
We demonstrate that explainable, knowledge-based big EO data analysis is possible via graphical semantic querying in EO data cubes.  ...  Users graphically create knowledge-based semantic models in a convergence-of-evidence approach, where color information is modelled a-priori as one property of semantic concepts, such as land cover entities  ...  Acknowledgments: We thank Steffen Reichel and Christian Werner for code contributions to the implementation. Conflicts of Interest: The authors declare no conflict of interest.  ...
