Hi Thomas<br><br><div><span class="gmail_quote">On 4/23/07, <b class="gmail_sendername">Thomas Rynne</b> <<a href="mailto:thomas.rynne@gmail.com">thomas.rynne@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
However, from what I have read I now think that I draw nodes manually<br>over the top of the GPS traces, using the traces a a guide.<br>Is that correct?</blockquote><div><br>You're right - you use the GPS traces as a guide. I think the node placement can be fairly rough. Often the GPS accuracy is only good to 7 - 10m, which is about the width of a residential street, so some guesswork will be involved.

</blockquote><div><br>Cycling along the road in both directions will let you average the traces and should get you closer to the centre - but I think your time would be better spent cycling along each road once, and getting more streets onto the map.

</blockquote><div><br>I usually create just enough nodes to follow the shape of the road. You'll need a node at every junction too. So, if it was a straight road with no junctions of it, you could get away with two nodes and one segment.

<br>Is there a web page I am missing?</blockquote><div><br>Try this wiki page: <a href="http://wiki.openstreetmap.org/index.php/Photo_mapping">http://wiki.openstreetmap.org/index.php/Photo_mapping</a> - it might have what you need.
<br><br>Good luck!<br><br>Olly<br><br></div></div><br>
