Pseudo-Mercator\UTM\BD09MC是投影坐标系,坐标表现形式为x、y。 WGS84\CGCS2000是原始坐标系,GCJ02\BD09是加密坐标系。 目前,谷歌、OSM等地图使用的是WGS84坐标系和Pseudo-Mercator...window 10 安装vs2013启动web项目报错Id端口不能启动iis https://www.cnblogs.com/leolion/p/3789732.html 如果我们想在...
Web Mercator 公开的小秘密 …… 这些ID又一石激起千层浪,看来整理总结下还是有点必要。 WebMercator如何定义? 我们知道,地理数据的坐标系一般有两大类,一是地理坐标系(GCS),是经纬度单位的椭球坐标系;二是投影坐标系(PCS),是平面直角坐标系。投影坐标系(PCS)的定义一般会包含两方面的定义信息: (1)基准面/Da...
