arcgis api for javascipt 加载天地图、百度地图

2024-09-01 16:28:33   220人阅读

写在前面的话：

1.百度地图是自己定义的坐标系统，wkid=102100.百度地图数据是加密的产物。下文将附上百度坐标与WGS84，谷歌等坐标系统转换方法（地理-地理），此方法并未亲测，据说准

2.百度地图可以直接加载经纬度坐标

3.百度地图如果加载的arcgis api中会出现坐标偏移，1.中已经解决了地理坐标转换，那么找到百度投影-地理坐标的转换方式，则arcgis就可以直接无偏加载了，网上很多方法，但是亲测不行。

4.天地图不是涉密数据，根据本文提供的类库,arcgis api for js可以直接加载。但是数据有略微的偏移

 

 

天地图的切片地图可以通过esri.layers.TiledMapServiceLayer来加载，在此将之进行了一定的封装，如下：

1、切片线划图——TDTLayer.js
