On 3 July 2018, the FFG-ASAP project Sen2Cube.at held its kick-off meeting in conjunction with the AGIT/GI_Forum conference in Salzburg.
Aside from the academic partner (University of Salzburg, Z_GIS), the project involves AMA(Agrarmarkt Austria),ZAMG (Zentralanstalt für Meteorologie und Geodynamik) and the university spin-off SpatialServices.
The Sen2Cube.at project will be taking very relevant steps towards building an Austrian data & information cube. It will exemplarily show that semantic content-based image and information retrieval (SCBIR) is possible in big Earth observation (EO) databases. This innovation will allow human 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). Planned tasks include:
- developing algorithms for systematic and automated semantic enrichment for Sentinel-2 images to reach a semantic level up to land cover types, ready for semantic content based querying
- identifying suitable database technologies to develop spatio-temporal modelling and querying techniques in semantically enriched EO databases using encoded ontologies to decrease the complexity of queries for human user interaction
- developing a Web interface for human-like queries based on spatio-temporal relationships and explicitly specifying spatio-temporal models for different envisaged user groups.
The data & information cube is generic, meaning it can be useful for multiple thematic domains. The potential will be demonstrated by developing different services in a generic, proof-of-concept environment for Austria. These services include enabling semantic content-based image retrieval, generating cloud-free mosaics for user-specified time slices and developing an App for location-based queries through time.
