你好，感谢你的联系。
我绘制这条路线的时候是参考了户外助手路网以及Strava的路网的，在当时应该是比较准确。当然，这么多年过去了，也许有些地方路线会有改道，需要大家一起来修正。
不过，我建议可以局部修正，而不是完全删除。毕竟基于路网的会比较准确，是多数人行走的路线。单一的一次行走的轨迹可能会因为GPS信号漂移，或者局部小路选择的不一样，而有些偏差。
谢谢！

My reversion deleted your work on fixing map errors. I'm really sorry for that. I made reversion because it is the simplest way to correct the offset problem. It's difficult to fix by hand and no tool can help.

Please go ahead to make changes.

I'd verified with GPS tracks from one local hiking track service (just like Strava). The result shows that the Bing maps has lowest offset in Guangzhou area among the maps services available on iD. You could make it as reference if needed.

Please don't modify features just base on aerial image. You changed the map to align Maxar Imagery. However Maxar Imagery has big offset. Your alignment just made the map worse.
