示例网址为https://iclient.supermap.io/examples/leaflet/editor.html#04_bufferAnalystService
示例缓冲区分析为线的缓冲区，我想做一个点的缓冲区，已经将BufferSetting中左边长度删去，也设置成了圆形的缓冲区形状，还将代码中的url改为自己的huanchongurl，将World:Capitals改为Chemical_Factory@EmergDS，把sql条件改为"Name='铝业化工厂'"
但是还是没有效果，不知道是什么原因，我的地图发布是按照经纬度的，而缓冲区是按米的，是不是这个原因？该如何更改？
改后代码为

服务什么的都是发了的。
