Distributed WebGIS model based on ArcSDE and SVG
基于ArcSDE/SVG的分布式WebGIS模型

Based on the analysis of the oilfield space objects and their attributes data, as well as the relationship between the objects, and combining with the data organization technique which was popular in ArcSDE spatial model currently, this paper proposed a distributed WebGIS model, which could unify the global space model and the local space models distributed on different regions. Using this distributed WebGIS model, GIS information about any kind of complex spatial object could be stored, data communication between client and GIS server could be carried out with the ArcSDE technique, and geographic coverages which were distributed on different regions could be displayed and managed in a global view window by SVG technique in the client. Based on this system model, this paper constructed the oil WebGIS platform model using metadata-driven technology to meet the actual demands of oil. Finally, implemented the distributed WebGIS platform. Currently, the platform has already been applied in Daqing oilfield.
