[Talk-us] Correcting DOT bridge coordinates

[Simon (Vsevolod) Ilyushchenko]

Hi,

I have taken US DOT bridge condition appraisal data and created a
regionated KML visualization: see post at
http://www.thedaysarenumbered.com . However, almost all bridges are
not geolocated correctly. I wonder if someone can recommend a way to
use OpenStreetMap to edit the bridge information so that, on one hand,
the bridges are added to the base layer if they are not there already,
and on the other hand, so that the corrected bridge coordinates could
be extracted and given back to DOT (as a way of saying thank you)?

BT, I was pleasantly surprised when the OSM California road dataset
that I downloaded yesterday proved to be much better than the one the
state of California provides.

Thanks,
Simon
