Paper Abstract

Nowadays, huge volumes of geospatial data and services are available and accessible to people all over the world. However, they are searched mostly based on keyword, which is inherently restricted by the ambiguities of natural language, which can lead to low precision and recall. In this paper, semantic share of geospatial data and services are studied based on ebXML registry. But ebXML registry specification doesn't take into account the registration of the semantic information. So we define how OWL DL constructs are mapped to ebXML registry information model (ebRIM) constructs without causing any changes in the core ebXML registry specification. After that, predefined stored procedures are provided in the ebXML registry for semantic search, which provide necessary means to exploit the enhanced semantics stored in the Registry. Then, geospatial ontologies in change detection application of remote sensing based on Global Change Master Directory, ISO19119 and ISO19115 are established. Finally, a prototype system is developed based on an open source-ebxmlrr to demonstrate the proposed model and approach.
