摘要: 针对城市勘测规划中需要将AutoCAD矢量数据与WebGIS发布的地图进行叠加分析的应用需求,本文提出了在两种异构数据中寻找同名节点相应位置的方法,建立了一种基于节点向量同名节点(无几何畸变)的快速转换模型匹配方法,并通过AO(ArcObjects)/ArcGIS Server发布地图服务使不同坐标系下的矢量数据与在线地图进行同步匹配,实现了在WebGIS平台下用户对矢量文件的在线审查、分析等功能,并以实例应用结果表明了该方法的有效性。

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
