Sentinel-2 Semantic Data Information Cube Austria

Data cubes seem to be a promising methodological development to deal with the big EO data challenge. The Sentinel-2 Semantic Data Cube Austria (Sen2Cube.at) goes beyond the current state-of-the-art and aims to build an Austrian data & information cube. The main goal is to show that semantic content-based image and information retrieval is possible in big EO image databases, allowing users to query and analyse EO data on a higher semantic level (i.e. based on at least basic land cover units and encoded ontologies). This includes: (1) fully automatic semantic enrichment of Sentinel-2 images up to land cover types ready for semantic content-based analysis; (2) the use of suitable database technologies to develop spatio-temporal modelling and querying techniques using encoded ontologies to decrease the complexity of queries for user interaction; (3) a Web interface for human-like queries based on semantic models of the spatio-temporal 4D physical-world domain; and (4) the demonstration of the potential of the generic data & information cube in future service developments based on different service types.
