You can start with the current OSM map, which I have found to have the
most relevant information.<br>
<br>
Simply using the name search, on the left, you can localize at least
the town, and zoom in to see if the streets have names. In Jacmel, for
example, the St Michel hospital was already there, all I had to do was
copy its coordinates in the spreadsheet. (I am new to OSM - one week,
so I don't know yet how you can most easily get coordinates from the
map, but if you need this, somebody else will certainly tell you. You
can click on data in the upper left menu, and see the properties of the
objects, which is already a way to get familiar with OSM tools.)<br>
<br>
In the opposite case, there is no information at all except the name of
the town, and maybe an address that can't be localized. In this case,
like I said in the wiki, I just put approximate coordinates (e.g. from
the town). My understanding of OSM is that, like in Wikipedia, the
information gets corrected and improved when it becomes available.
Anyone that detects something wrong or imprecise for the first time can
then correct it himself.<br>
<br>
Of course, this is a simplified explanation, but I think that in this
context, getting at least some info as quickly as possible is the most
important. I am also hoping that more people can join in.<br>
<br>
Then it can be refined with anyway you can think of and imagine,
internet search, etc.<br>
<br>
Beside this mailing-list, you can also get help or coordinate search in
a chat tool on the spreadsheet page (click on upper right arrow), and
the irc channel.<br>
<br>
Thank you again,<br>

<pre wrap="">happy to start on that. What's the best way to determine those
lat-long points. Just internet research, or is there any other more
direct approach?

<pre wrap="">Margie,
Even before learning OSM tools, you can be very useful by looking up the
coordinates of Haiti hospitals.
Please see :
<a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/News">http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/News</a>
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

<pre wrap="">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.

<pre wrap="">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:
<a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/New_Mapper">http://wiki.openstreetmap.org/wiki/WikiProject_Haiti/New_Mapper</a>
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:
<a class="moz-txt-link-freetext" href="http://www.youtube.com/watch?v=D6pBBK1SHh0">http://www.youtube.com/watch?v=D6pBBK1SHh0</a>
<a class="moz-txt-link-freetext" href="http://www.youtube.com/watch?v=Oio1jY8WNig">http://www.youtube.com/watch?v=Oio1jY8WNig</a>
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: <a class="moz-txt-link-freetext" href="http://irc.openstreetmap.org">http://irc.openstreetmap.org</a> and we can answer
questions and help you out.
Thanks again for willingness to help out with mapping!
Regards,
Katie Filbert
