基于WMTS标准的2.5维电子地图的构建

2.5维数字地图既具有三维数字地图良好的表现效果,又具备数据量小、网上传输速度快的优点,满足了在现有的网络环境下对三维地图的快速浏览访问,在传统二维地图和真三维地图之间起到了很好的承上启下的作用。本文针对阜新市二维矢量数据和属性数据,利用3ds Max软件对研究区域建模并渲染成图,然后,在PhotoShop软件中进行图幅拼接,最后制作成瓦片地图与矢量图叠加发布,以便实现在Web端对2.5维电子地图的浏览、查询和空间分析等功能,并重点研究了基于OGC的WMTS标准和瓦片金字塔技术的标准化切图制作、发布、调用方法。

2.5-Demensional Map Publishing Based on ArcGIS Server

A 2. 5-dimensional map has advantages in good performances similar to the three-dimensional map,small amount of data and high transmission speed over the Internet,which satisfies the demands of quick browsing and access under available network environment. It serves as a good link between traditional two-dimensional maps and true three-dimensional maps. In this paper,we used 3ds Max software to model and render the study area with two-dimensional vector and attribute data in Fuxin city and mosaicked maps in Photoshop software. Finally,we made tile maps,stacked vector maps on them and released,in order to achieve 2. 5-dimensional electronic map browsing,query and spatial analysis on the Web. We also studied the WMTS standards based on the OGC and the methods of normalized map cutting,publishing and calling based on tile pyramid technology.
