To clean up <a href="http://maps.paulnorman.ca/imports/review/fresno.png" target="_blank">http://maps.paulnorman.ca/imports/review/fresno.png</a> I would<br>
start by deleting most of the data.<br>
<br>
A couple of users, one local, have commented that the issues with the import<br>
make it difficult to edit in the area. I really can't see a way short of<br>
deleting it.</blockquote><div><br></div><div>Do those individual polygons have any useful information on them (addresses, for example)? If so, we should generate addr points from their centroids.</div><div><br></div><div>
Either way, we could save useful OSM information by creating a new polygon from the outside edges of each block. basically, remove all overlapping nodes except the ones on the outside. This way we maintain (semi-)useful landuse information and remove the extremely noisy tax plat information that's there already.</div>
