|
Aiming at the demand of national environmental monitoring information construction, combined with the demand of national environmental monitoring operation, national environmental monitoring spatial data platform has been developed. According to the disciplines of standardization, stability, reliability and expansibility, we designed and realized the management and operation of national environmental monitoring spatial data platform based on the large commercial relational database system and Spatial Data Engine(SDE). The spatial database platform included four types of spatial database: basic topographic database, thematic spatial database of environmental monitoring, environmental background database and remote sensing image database. Compositively making use of GIS technologies, database technologies and system integration and so on, we constructed spatial database platform with unified projection, coordinate system and data structure, realized seamless and continuous map manipulation between different scales, formed the abilities of management and update of massive spatial data, provided stable and robust foundation for future development and construction of environmental monitoring operation systems and information share services based on GIS and internet/intranet.
