Hi Nora
Sorry for the delay in reply, getting situated in Jerusalem for this month.
In Haiti (and elsewhere) I'm involved in OpenStreetMap
[http://wiki.openstreetmap.org/wiki/WikiProject_Haiti]. The Humanitarian
OpenStreetMap Team [http://hot.openstreetmap.org/weblog/category/haiti//]
organized a remote response following the quake, and over the past year has
been
working with COSMHA, the local OpenStreetMap organization. So all the data
there
has been collected within OpenStreetMap, using both GPS survey and aerial
imagery digitization (which includes Bing imagery, and other sources, but not
Google because of licensing issues). Slum boundaries would be known by the
local
mappers; the definition of a slum in Haiti is not universal, but in short, I
believe they're applying the "local" definition of what constitutes an informal
settlement.
Where exactly did you find this kmz? I'm happy to coordinate and connect you
with the team in Haiti, and see if we can come up with more useful data for
your
research.

Haiti slum kmz?
Hi Mikel,
I am working as a geographerin Haitiat the Centers for Disease Control
officehere. I came across your kmz of slums in thePort-au-Prince area, but I
couldn’t find any background of how you created it. Canyou tell me a little
more
about how you defined the boundariesand differentiated which neighborhoods were
or weren’t slums?In terms of the actual processing of the data–did you digitize
the boundaries on Google Earth?
The reason that I’m curious is because I am working onthe spatial epidemiology
of tuberculosis transmission in places with really high population density like
IDP camps and slums.I’ve been using the IOM’s census of camps, but hadn’t found
a parallel source of data for slums until I came across your file. Any
additional information you can provide would be greatly appreciated!
All the best,
Nora
