Hi all -<br><br>We've had a request from our field team for the most current data showing<br>road obstructions, e.g. through landslides or fallen buildings, at a<br>national level for Haiti. Ideally each location would be given a source and<br>
a date. Can anyone advise on the best place to look please?<br><br><span>I've seen the obstacles layer here (<a href="http://haiti.openstreetmap.nl/" target="_blank">http://haiti.openstreetmap.nl/</a>) but</span><br>don't know how to extract this as a data layer.<br>
<br>BTW: this is where the value of good attribution/tags really shows; the<br>developments here are very welcome:<br><span><a href="http://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Tags" target="_blank">http://wiki.openstreetmap.org/wiki/Humanitarian_OSM_Tags</a></span><br>
<br>I'd also like to say that our field team has been making much use of the<br>excellent OSM roads data (via Geofabrik) for in situ mapping for SAR teams,<br>UNOCHA, aid agencies
and in responding to specific location requests - it's<br>much appreciated on the ground.<br><br>Thanks and best wishes,<br>Nick.<br><br>Nick McWilliam<br><a href="mailto:nmcwilliam@mapaction.org" target="_blank">nmcwilliam@mapaction.org</a> / skype nickmcw / +44 77 7379 7471 <br>
