On this page you can execute stSPARQL queries against the Strabon backend. The dataset is based on the following ontologies: Corine Land Cover, Greek Administrative Geography (Kallikratis), Linked Geodata, and Geonames. We also use the DLR and NOA ontology we developed for the in the context of the European FP7 project TELEIOS. The acquired data are then annotated using the stRDF model and can be queried using the stSPARQL query language. On the left sidebar, some example stSPARQL queries are provided.
