Paper Abstract

Metadata plays important roles in the description, definition and exploration of geospatial data, therefore, underpinned greatly geospatial data exchanging and information sharing. We proposed here a metadata-based method for modeling geospatial objects. In our method, geospatial data managing was divided into three phase within a data modeling hierarchy. Geospatial metadata modeling phase constructed geospatial information model which form the underground of geospatial data management. Geospatial data model development was based on it and defined the data object and relationship between each others. On the top of the architecture was open-ended tools and applications used to support metadata design, spatial data model design and domain-specific application development. An exemplificative spatial data model demo was presented to argue the availability of this methodology.
