生活随笔收集整理的這篇文章主要介紹了 SuperMap IClient for Leaflet 加载高斯克吕格投影三度分带CGCS2000大地坐标系WMTS服务小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

SuperMap IClient for Leaflet 加載高斯克呂格投影三度分帶CGCS2000大地坐標系WMTS服務

難點所在
- 加大帶號高斯克呂格投影三度分帶CGCS2000大地坐標系
- 不加大帶號高斯克呂格投影三度分帶CGCS2000大地坐標系

難點所在

Leaflet加載WMTS服務（球面）的是很簡單的，但是加載投影坐標系的一直以來比較迷惑，故此，寫出來最常用的情況。
關于數據的說明：
采用的數據是江蘇片區的影像數據；
