Mapping Network Relationships from Spatial Database Schemas to GML Documents
Keywords:Spatial database, spatial modeling, GML data
AbstractSpatial data encoded in GML documents are used in various applications and are especially suited to storing, manipulating and exchanging geographic information. However, a large share of currently available spatial data is stored in spatial databases. This article presents a method to map arcs and nodes, organized in a network using spatial relationships, from a spatial database to a GML document. Specifically, a geographical conceptual schema and the corresponding GML schema are used as guide to retrieve and reorganize networking information found in the spatial database, thus generating a GML document. The proposed methodology is verified in a case study, in which networking relationships from real-world databases are mapped to GML documents that can be queried using standard XML languages such as XPath and XQuery.
