<br></div>The talk will (briefly) touch on persistence at other scales, by looking at individual roads, road networks and trees. All themes for planned blog posts which I havent written.<br><br></div>Regards,<br><br>Jerry<br>

Just another short note about broken software: The Export button on the OHM website is calling the OSM api instead of the local website - if you've been getting garbage XML, this is why. Should have it fixed this week.<br>
<br>
Also a quick note that David Evans will be presenting on the OHM Friday at State of the Map Birmingham at 14:20 GMT. If you are attending, consider dropping into the session and showing some OHM support! I'm sure there will be plenty of opportunity for talks and ideas swapping over a pint after.<br>
