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:

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
