Resumo:
The huge volume of spatial data available in the Web has increasing rapidly. Currently,
the Web has been used not only for searching documents but also for service provision,
known as Web services. These services are published in a directory, and may be
automatically discovered. Particularly, in the spatial domain, the possible use of such
services has demanded research on how to distribute and interoperate spatial data.
Therefore, Spatial Data Infrastructures (SDI) have been proposed in order to tackle
these problems. However the lack of semantics in such SDI is still an open issue. In this
dissertation, we propose SWS-GIS, which is a semantic SDI using service-oriented
architecture based on Web services. SWS-GIS enables distributed spatial queries over
catalogues, which take part in a federation of both spatial data and services. The
federation data model is according to a hierarchical ontology, which enables concept
mappings.
