| 摘 要： | 三维建筑物是三维电子地图的重要组成要素,现有的网络地图普遍采用Web GL技术在地图上展现建筑物三维效果。本文则采用开源纯Java Script技术的OSM Buildings三维建筑物引擎实现在传统二维电子地图上添加三维建筑物并支持在浏览器中以无插件的方式浏览3D场景。全文详细叙述了三维建筑物所用底图数据的采集、校正、投影以及将底图数据转换成OSM Buildings所支持的Geo JSON格式的过程。

| Abstract: | 3D Building is an important component of 3D map, while most maps show 3D buildings by WebGL technology .Like Web-GL, OSM Buildings is an open -source 3D building engine developed by JavaScript .This paper adopted OSM Buildings to add 3D buildings into the traditional 2D map and do this without plug -ins.This paper described the collection , correction, and the projection of 3D Building’s base maps and the process of transforming the base maps into GeoJSON format supported by OSM Buildings . |
