Knowledge-based search for Earth Observation products

Podwyszynski, Marius (2009) Knowledge-based search for Earth Observation products. Diploma, Universität Passau.



This diploma thesis considers both, theoretical and practical aspects of the semantic modelling approach for the EO domain. Firstly, it briefly introduces the EO data management at the DFD and then continues with the problem analysis based on real-life usecases used as a starting point to create a common high-level information model of the EO domain. Next, the common high-level information model can be formally speci�ed into an ontology for the EO domain that reuses common terminologies from earth sciences. Furthermore, the user access to the developed ontology is presented in the EOLOsearch web demonstrator. Finally, the feasibility of the semantic modelling approach for the EO domain is evaluated based on the developed ontology and its web demonstrator considering several quality criteria that apply for the EO domain.
