Abstract

Geography Markup Language is a de facto standard developed by OGC to standardize the representation of geographical data in XML, which makes the exchanging and sharing of geographical information easier. With the popularity of GML technology, more and more geographical data is presented in GML format. This causes the problem of how to efficiently store GML data to facilitate its management and retrieval. An approach to store and query GML document based on model-mapping is proposed in this paper. The proposed approach mainly focus on non-schema GML documents, but it is also applicable to GML documents with corresponding schemas. A GML document is first parsed, and a document tree is generated. Then the tree nodes are analyzed and processed, and the schema mapping is established for storing GML documents into object-relational database with structural information preserved. Spatial data analysis and non-spatial data query are supported on database for document. Experiments show that the proposed approach is feasible and efficient.
