Hi, all,<br>
<br>
Many of the administrative boundaries in my area follow roads (or vice<br>
versa). (E.g. <a href="http://osm.org/go/Zcll6ubE?layers=B000TTF" target="_blank">http://osm.org/go/Zcll6ubE?layers=B000TTF</a> ) It seems<br>
like the TIGER import has a separate list of nodes for the two ways<br>
(one administrative and one road), but the nodes are at identical<br>
locations. This makes Maplint and Potlatch complain about duplicated<br>
nodes, making it hard to distinguish real map lint from this type.<br>
<br>
It seems like the TIGER data for the administrative boundaries is<br>
pretty good, so I don't want to touch those nodes.<br>
<br>
What's the best thing to do with this situation:<br>
1. Leave it as-is.<br>
2. Combine the nodes so they're not duplicated. (Do bots sometimes<br>
do this? How would a person do it in Potlatch?)<br>
3. Offset the nodes of the road so it follows the same line but no<br>
longer forms map lint.<br></blockquote><div><br>How about 4: delete the TIGER imported administrative boundaries?<br><br>In my experience a) they're not very good, and b) we should be using boundary relations anyway. <br>
