At first I thought they were state borders, but I'm seeing the lines running through the middle of states, too (here <a href="http://www.openstreetmap.org/?lat=42.001&lon=-120.048&zoom=9&layers=B0FT">http://www.openstreetmap.org/?lat=42.001&lon=-120.048&zoom=9&layers=B0FT</a> it runs vertically through the middle of Oregon). Then I thought they were tile boundaries, but that's not consistent, either. Even weirder is on the California-Nevada border, there are two vertical lines right next to each other, not always parallel.

I downloaded that area in JOSM but all I saw was a single state border way. It doesn't seem to have a source in the OSM data, so maybe it's something caused by the conversion to pgsql or by the renderer itself (maybe a projection issue)? I don't think it's related to the recent mod_tile changes, because as far as I know that only affects how the tiles are stored and served, not how they're rendered. (If I've said something stupid, please forgive me. I *think* I understand the process...)<br> <br>Any thoughts, anyone?</blockquote><div><br class="webkit-block-placeholder"></div>railtracks ?</div><div><br class="webkit-block-placeholder"></div><div>Artem</div><div><br></div><div><blockquote type="cite"><br><br>Karl<br><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">talk mailing list</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="mailto:talk@openstreetmap.org">talk@openstreetmap.org</a></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk">http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk</a></div> </blockquote></div><br></body></html>
