Abstract: In order to meet the needs of the application that the AutoCAD vector data and the maps published by WebGIS need to overlay analysis, this paper proposes a method to find the corresponding position of the same name point in two kinds of heterogeneous data, and establishes a method based on the same point of the node vector (no geometric distortions ), and the vector data of different coordinate systems are synchronized with the online map through AO (ArcObjects)/ArcGIS Server.This system can realize the online review and analysis of vector files under WebGIS platform. The application results show that the method is effective.

Key words: dynamic vector data, fast matching, correspondence nodes, online map, Uploadify
