</div>The problem with WMS layers is you loose the meta information that<br>
already exists, or you need to do a lot of work to add it after<br>
tracing.<br>

</div>WMS layer isn't the only option, and in my opinion not the best one as<br>
you loose all the meta information.<br></blockquote><div> </div></div>Yup... i knew you were going to say that...<br><br>If you want the meta data, you can have it in a separate database. :) And donate all your corrections back to the source provider.<br>
<br>Using the FME GIS application from SAFE. This product provides that option. (All i know is that it works.. but i dont know how it does) ... others do.<br><a href="http://www.safe.com/">http://www.safe.com/</a><br><br>
Natural Resources Canada will be using it as a way to enhance the source dataset with the more accurate OSM data, and creating a DIFF dataset. (which shows the difference between the source versions, so then the next available dataset will be much smaller, as it only includes the 'missing data' )<br>
<br>And in return for that, Natural Resources Canada is creating .osm files the size of nice NTS tiles (and smaller quad-tree tiles) ie. .1x.1 degrees for those areas with a hi-density of data. (so local people can view all of the features into a single combined .osm file)<br>
<br>Osmosis can also do this, but i think an algorithm still needs to be made to line up with degree tiles. (which tile-splitter can possibly help).<br><br>I hope im saying that correctly. <br><br>So using a combination of both, the WMS layer from the source data & the .osm files. It should make for more happy campers all around.<br>
<br>Cheers,<br>Sam<br><br>p.s. Some folks on the main #osm IRC chat might be happy discuss it also :-)<br><br>
