Abstract


The spatial information presented by the traditional two-dimensional geographic information system is more abstract, which is unable to satisfy the needs of people who want to use the spatial information to understand and reconstruct the actual world.3D GIS can display the spatial information more intuitively. With the development of network technology, storage technology, virtual reality and the other computer technology, using three-dimensional form to describe the cognitive object becomes possible. Meanwhile, GIS development from 2D to 3D is also faced with many problems, such as sharp increase of spatial data, the extremely complex of data structure and effective sharing and interoperability of 3D spatial data. The emergence of grid technology provides a new approach to solve these problems, and provides technical support to implement the architecture of 3D digital city. This paper based on the analysis of grid technology, CityGML specification and 3D GIS technology, carries out the exploratory research to the problems of access integration and interoperability of 3D urban data in grid environment. The main research work and achievement as follows:1) Through the study on the related concepts, enabling technologies and the architectures of grid technology, for the complex data structure and large volumes of urban 3D spatial data, this paper proposed a new grid architecture suitable to the 3D urban spatial service based on the WSRF (Web service resources framework) framework.2) Discussed the OGC standards and the CityGML specification to the digital city proposed by Open Geospatial Consortium, designed a kind of urban 3D data stream transmission mode based on the CityGML standards and SOAP message package, and provided the 3D urban spatial data interoperability methods in grid environment in the form of grid services.3) According to CityGML specification and its’properties of each modules, designed the 3D urban spatial database based on CityGML and Oracle Spatial database.4) Built the prototype system for the 3D cities information grid platform based on the Globus Toolkit, by creating CityGML_Import and CityGML_Export grid services to achieve the conversion and interoperability between the Oracle Spatial data and CityGML document.
