2.5维地图制作算法研究与实现

Research and Implementation on Algorithm of 2.5-Dimensional Map Producing

随着网络技术图形学技术地理信息技术的不断发展与普及三维GIS与webGIS已经成为地理信息系统行业的主流发展方向。但基于成本、技术等诸多因素的限制,两者尚未广泛结合运用与GIS产品中。论文提供一套基于SHP文件的2.5维建筑物数据生产方案,以将低B/S系统三维可视化的技术难度与生产成本,填补当前GIS市场中相关产品的空缺。

With the rapid development of network technology、graphics technology、geographic information technology,popular three-dimensional GIS and webGIS has become the main direction of GIS industry.However,Due to cost or technology and many other factors,combination of the two is not widely used in GIS products.My paper provides a set of data generation Program based on 2.5-dimensional structures SHP file,which can the lower the technical difficulty and production costs of the B / S system three-dimensional visualization,fill the vacancies in related products of current GIS market.
