Integrated Management of Distributed Heterogeneous Raster Spatial Data

We dicuss the key technology of implementing the seamless integration and the service for distribute heterogeneous raster data.Firstly,the architecture for integrating of distribute heterogeneous raster data is designed.Secondly,the distribute raster spatial index and the logical pyramid data structure are presented.Finally,according to these methods,a GeoGlobe-based prototype is tested and some advices are discussed.
