前言
编写这个专栏主要目的是对工作之中基于Cesium实现过的功能进行整合,有自己琢磨实现的,也有参考其他大神后整理实现的,初步算了算现在有差不多实现小130个左右的功能,后续也会不断的追加,所以暂时打算一周2-3更的样子来更新本专栏(尽可能把代码简洁一些)。博文内容如存在错误或者有可改进之处,也希望在这里和各位大佬交流提高一下。

介绍
专栏内容本着尽可能简洁的原则,本篇文章为地图纠偏demo第1篇,主要是实现加载 Geoq智图 的Arcgis地图服务,大致效果如下:

关键代码
function transformProjection(provider) {
let webMercatorTilingScheme = provider.tilingScheme;
let projection = webMercatorTilingScheme._projection;
