[OSM-talk] Duplicate nodes in the US

[Nakor]

    Hello,

On a regular basis I have to write to some contributors that use 
automatic methods to merge nodes in the US so I though I would copy my 
message here so everyone is aware:

Please do not run automatic merge tools in the US. Doing this you will 
connect entities that should not (e.g. river with road). This is due to 
the source of the imports that have duplicate nodes for different type 
of entities. If you want to fix duplicates in the US you need to review 
your changes one by one.

Also to avoid such mistakes you can use the JOSM validator plugin that 
sorts duplicates by type of ways i.e. highway duplicates, boundary 
duplicates, waterway duplicates, powerline duplicates, ....

  Thanks in advance,

N.
