Abstract

With the development of earth observation technology provides more geo-information, a large amount of spatial data with different format can be obtained through the Internet. So in the construction of spatial data infrastructure and digital earth, how to effectively utilize and integrate the spatial information to fulfill the need of people from different departments and fields in the distributed environment is an important issue. Based on the web coverage service specification provided by OGC, a new coverage data service architecture including multi raster data source(MRDS), raster data engine(RDE), raster transfer object (RTO), raster business object(RBO), WCS business object (WBO), WCS business interface (WBI) and WCS Facade (WF)is put forward, which can effectively publish many kinds of imagery and DEM data, which cab be deployed in distributed network environment, published through a unified map definition file and implemented GetCapabilities, DescribeCoverage and GetCoverage interface. Some key technologies including GML coverage profile process and multi WCS combination are described in detail. Finally, a client which could get imagery and DEM data from Web coverage Service for 3D visualization is designed and implemented. It is proven a feasibility way that Web 3D rendering by means of integration of multi Web Coverage service.
