Abstract
Although local, regional, and global SDIs have undoubtedly improved sharing and synchronization of geospatial information across diverse resources, there are limitations in currently implemented SDIs and it may still be difficult to find needed data sources from the currently implemented SDIs. The differences among the semantics used in diverse data sources represent a major problem in spatial data sharing and interoperability. Geospatial Semantic Web was recently proposed in the geospatial community to overcome the semantic heterogeneity problem of geospatial data. Geospatial Semantic Web provides computers meaningful geospatial contents, thus allowing geospatial data to be discovered, queried, and consumed automatically by computers. In this chapter we introduced the main technologies used in the Geospatial Semantic Web architecture: 1) ontology, 2) semantic descriptions of geographic information by ontology, 3) ontology-based catalogue service, 4) web service discovery, and 5) web service composition.
