摘　　要：三维GIS技术已经逐渐发展成熟,其对客观世界的表达能给人以更真实的感受,然而三维GIS软件所需数据是海量的。由于遥感技术的发展,纹理数据的获取和处理已经变得容易和快速,而对于矢量数据的采集、存储是一个非常艰巨的工作,如何在短期内获取海量、精确的矢量地理信息数据,减少数据采集的费用和时间成了一大难题。通过基于网络的地理编码来查询获取矢量点状地理信息,将地理信息存储到本地数据库,并且将数据应用到系统中进行快速定位显示,实现地理位置的实时定位和查询,为各种专题三维GIS软件开发提供服务和扩展功能。3D GIS technology has been developed gradually mature, 3D GIS for the expression of the objective world can give people more realistic. However, the required data of 3D GIS software is massive, due to the development of remote sensing technology, the acquisition and processing of texture data has become easy and fast, collection and storage of the vector data is a very difficult task, It＇s a major challenge how to get massive, accurate vector GIS data in a short time, and to reduce the cost and time of data collection. By Web-Based Geocod- ing querying the geographic information of point features to store the geographical information to a local database. Data is applied to real-time positioning, quickly Locating and displaying in 3D GIS software. It provides services and extension function for developing various special 3D GIS software.
