Map projections A map projection is the means by which you display the coordinate system and your data on a flat surface, such as a piece of paper or a digital screen. Mathematical calculations in the map projection are used to convert the coordinate system used on the curved surface of ear...

WGS-84 Web墨卡托坐标系 这个坐标系资料太多了,各种官方代号,由于更新太为频繁,是一种相当成熟的坐标系,如今主流的Web地图几乎都是使用的Web墨卡托,如国外的 Google Maps,OpenStreetMap,Bing Map,ArcGIS 和 Heremaps 等,国内的百度地图、高德地图、腾讯地图和天地图等也是基于Web墨卡托。 WGS-84 UTM坐标系 UTM投影...
经常碰到这两个概念:Geographic coordinate system和projected coordinate sys tem 1、首先理解Geographic coordinate system,Geographic coordinate system直译为 地理坐标系统,是以经纬度为地图的存储单位的。很明显,Geographic coordinate syst em是球面坐标系统。我们要将地球上的数字化信息存放到球面坐标系统上,如何进行操作...
Map Coordinate System 空间参照系统和地图投影 导读:正如上一章所描述的,一个要素要进行定位,必须嵌入到一个空间参照系中,因为GIS所描述是位于地球表面的信息,所以根据地球椭球体建立的地理坐标(经纬网)可以作为所有要素的参照系统。因为地球是一个不规则的球体,为了能够将其表面的内容显示在平面的显示器或纸面上,...
