Abstract :
Spatial data infrastructure is the main data base of e-government, and provides spatial data even the geospatial services guarantee for e-government decision support. The traditional spatial data infrastructure can meet e-government for spatial data visualization and query browsing needs, but the complex spatial analysis demand of disaster assessment and other professional services, spatial data infrastructure reflected inadequate. After analyzing the relationship among SDI e-government and geospatial services, a common spatial services aggregation model is designed, this provides the ability to conflate of geoprocessing service chains dynamically Support e-government decision-making. The experiments represent lightweight spatial analysis solutions could be construct flexibly.
