The following query will create an XML file of everything tagged with barrier=obstacle in the Haiti area: http://www.informationfreeway.org/api/0.6/*[bbox=-75,17.5,-71,20.2][barrier=obstacle] Similar queries can be used for other tags impassible=yes, blocked=yes etc. The data is normally very fresh, being just a couple of minutes behind the main OSM database. 80n > * The thread on CrisisMappers has more info on other sources of data, and > new imagery coming out. > > -Mikel > > == Mikel Maron == > http://mapkibera.org/ > +254 (0) 724899738 > [email protected] > > > ----- Forwarded Message ---- > *From:* Nick McWilliam <[email protected]> > *To:* [email protected] > *Cc:* [email protected] > *Sent:* Wed, February 3, 2010 3:05:33 AM > *Subject:* [CrisisMappers] Haiti: road obstruction locations > > Hi all - > > We've had a request from our field team for the most current data showing > road obstructions, e.g. through landslides or fallen buildings, at a > national level for Haiti.
