Cover Story: The intelligent integration of earth observation (EO) data, primarily represented in the form of raster data cubes using knowledge graphs (KGs), plays a crucial role in managing geospatial data heterogeneity and enhancing semantics. This paper introduces a framework that conceptually defines a semantic model for raster data cubes, extending GeoSPARQL ontology. This model combines raster data cube semantics with feature-based geometry and spatial relationships, enabling spatiotemporal queries using SPARQL through ontological concepts. The implementation of this framework involves virtual querying, which refers to dynamically constructing the geospatial knowledge graph during the querying process. This approach eliminates the need to pre-translate all data into a KG, thereby reducing redundancy and cutting storage and processing costs. View this paper
