Hi,
I have the same problem. Brad Neuhauser said on the crisismapping list
that lot of work has been done before digitalglobe was available. In
particular, an old CIA map has been used, there are a lot of objects
with a source tag refering to it. I've started to delete individual
buildings which are obviously badly off. I'm not sure whether the
digitalglobe imagery is correctly rectified, thought. Anybody?
Regards
Karl

All,
I understand we are all busy, but I have some Haiti questions. The
area around Jacmel in the south appears to be very messy at the
moment, and I am only focusing on roads and basic infrastructure. The
roads seem very far off, and at times some do not even seem to point
to an artifact I can see in the imagery.

I have tried cleaning it up using the DigitalGlobe imagery, which I
have assumed to be the best. Am I wrong here? What are other people
using and what are the current recommendations? Am I doing a bad job
or wasting my time aligning the roads if they are this far off? I
realize my use of DG may bias me, and I have not taken the time to
compare. That being said, I heard it was the most recent and expansive.
Sorry for the newbishness here. I just want to help, and I heard
Jacmel and all points south will be needed soon.
Regards,
