Abstract
For a long time, the GeoSpatial data in GIS exists the heterogeneity of data model, data format and meaning. Most data sharing still needs data integration between different application systems for using now. This results a problem of GeoSpatial data interoperability. OGC Geographic MarkUp Language (GML) is a solution of data sharing. It will be prevailing in the future that providers of data use Web Feature Service (WFS) to share data in GML format. Although GML is in an open and standardized format, there is still a semantic integration problem in data sharing. Users could not search the meaningful data sources with simple text query.
This thesis focuses on”Semantic Web” and “Ontology”, and suggests that OpenGIS Web Services should refer to an ontology formalized by experts with domain knowledge. Users could search appropriate data service according the ontology. This piece of work reviews the related researches to propose an ontology-based OpenGIS web service architecture, and applies to a disaster management system as an illustration. This research has built an ontology of spatial disaster planning for the OpenGIS web service. Such ontology defines many classes and relation among these concepts of the knowledge of disaster and urban planning and be able to present the geographic objects in the real world.
This thesis use Eclipse IDE, uDig application and IBM toolkit with Java language to implement a GIS, called “Ontology and Open GIS Browser (OOGB).” Users could use OOGB to retrieve the OpenGIS web service, query and reason ontology in GIS. Using the architecture described in this thesis, the users in GIS community could retrieve meaningful data services based on ontology.
