Hi,<br>Nice map. im using the OpenStreetMap KML overlay to look at it on Google Earth.<br><br>Regarding contours, if your plannng on using the map with an underwater GPS device. i would recommend using a marine charts map as an overlay, so to get your depth contours. Just as you would use a SRTM contour overlay for on land use.<br>
<br>Obviously, you cant copy from that marine charts map, but of course, from entering in waypoints & rembering what the point was. It helps.<br><br>I dont know where there are depth contours available for the planet. It would be AWESOME to find some, so then they can be used with the Groundtruth program. if you have a source which is compatable, please to share. It would be great to get whatever contours are available.<br>
<br>Also, i noticed that a few features didnt render in mapnik.<br><br>the tag might be appropriate<br><a href="http://wiki.openstreetmap.org/wiki/Tag:historic%3Dwreck">http://wiki.openstreetmap.org/wiki/Tag:historic%3Dwreck</a><br>
with the addition of layer=-1<br>then the addition of ele=-50<br>(as the default is meters) .. or whatever the actual depth is.<br><br>IMO, Cheers,<br>Sam<br><br>P.S. the seamap project is part of this topic as this interesting :)<br>

<br>
I was playing around exporting OSM to KML. I did this underwater map<br>
which is intended for scuba diving. Various points of interest and<br>
underwater guide ropes are shown. I used python to do the conversion.<br>

I have used parts of the proposed tagging:<br>
<br>
<a href="http://wiki.openstreetmap.org/wiki/Proposed_features/scuba_diving" target="_blank">http://wiki.openstreetmap.org/wiki/Proposed_features/scuba_diving</a><br>
<br>
I would be interested in any comments, for example what is the best way<br>
of storing and tagging depth contours in OSM or if anyone wants to buddy<br>
for underwater mapping in the UK (mainly southern UK is my preference).<br>
