连通性修复问题：
请问在使用modify_conn函数进行连通性修复，产生以下报错，是因为原始路网的问题么？
有什么好的解决意见，谢谢！

你的路网点层不是用gotrackit依据线层生产的把？检查一下node层中是否有部分节点没有在线层的from_node和to_node中出现,如果有，请把这部分节点删掉

[zdsjjtTLG]

used_node = set(link_gdf['from_node']) | set(link_gdf['to_node'])
node_gdf.reset_index(inplace=True, drop=True)
node_gdf.drop(index=node_gdf[~node_gdf['node_id'].isin(used_node)].index, inplace=True, axis=0)
node_gdf.reset_index(inplace=True, drop=True)

已解决，感谢！

路网优化对数据的坐标系有要求吗

[ren-max11]

没有报错，但是原文件没有被修改，是因为出现NAN值吗？

这不是被修改了吗？？？node_id本来都是5位数，现在不是变成两位数了吗？你的原来的link表的from_node、to_node的值有一部分在node表里面找不到..........才会导致空值

[ren-max11]

代码看起来确实修改了，但是打开输入的link和node，还是原来的id

[zdsjjtTLG]

你肯定要自己再存一次新文件呀

[ren-max11]

哦哦哦，sorry，明白了
