Margie,
Even before learning OSM tools, you can be very useful by looking up the
coordinates of Haiti hospitals.
Please see :
http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/News
There is a shared spreadsheet to fill. And people that already know OSM
can then use the coordinates you could find into OSM.
Thank you,
Jean-Guilhem

I've got a GIS background. Happy to get up to speed on OSM. What can I
do to help Haiti relief and mapping efforts?
I plan to be at the CrisisCamp DC on Saturday. I can attend in the
afternoon.

Margie,
I will be there and can give a tutorial on Saturday. If you want to
help with OSM before then, then the new mapper guide might help:
http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/New_Mapper
What we've done up until now is digitize streets and features, looked
for collapsed buildings (less priority now), and for camps (high
priority now). We used imagery from GeoEye and DigitalGlobe, but the
resolution was only so good. We now have access to .15 m resolution
imagery from Google, with their permission, we can trace from in
OpenStreetMap.
What I'm doing now (and you can do) is going back through what's been
done in Port-au-Prince and other areas and identifying camps. We
missed many before, but are apparent in the new imagery.
I am using Potlatch, the web-based editor (the edit tab on the OSM site).
We have a couple video tutorials that might help you with using Potlatch:

For camps, I am simply drawing them as polygons. Tags I use are:
* tourism = camp_site
* refugee = yes
* source = Google
(others on this list may be able to suggest better tags that these,
but these work)
We can also do cleanup of the existing data, using the new imagery
(e.g. some roads need to be fixed).
If you have questions, you can e-mail the osm-talk list. Or feel free
to join us on live chat: http://irc.openstreetmap.org and we can
answer questions and help you out.
Thanks again for willingness to help out with mapping!
Regards,
Katie Filbert
