Research On Spatial Data Integration Orientated To Spatial Data Warehouse

With further growing complexity of spatial data,present data database and data analyzing tool cant give enough help to make decision,so it is necessary to establish many spatial data warehouses about lot of history data and different scales.Based on present database,spatial data warehouse and spatial data integration,the article discusses thoroughly about process of building the model of the spatial data warehouse and bring out systematically two aspects on data integration orientated to spatial data warehouse:one about data integration of different data resources,the other about data integration of different scales.
