Hi,
Having just completed one of the squares for this task, a few notes
which may help (It's not easy, so be prepared to take your time & do
your best);
If using JOSM, load not only the imagery linked to the task, but also
Bing or whatever imagery was first used. By hiding the different layers
you can then compare the before (Bing?) & after imagery to see how the
building has changed.
Alignment - slightly different to the existing tracing. As usual no gps
traces available, but always worth trying.
History - Be prepared to look at the history of buildings - on my square
someone had been creating new buildings using the post disaster imagery
12 hours before I started - they were only tagged as building=yes, so it
took me a few minutes of investigation to work out what had been done
(Ctrl+h in JOSM will bring up the history of a selected node or way).
Tents - I'm fairly certain that at least two of the buildings added 12
hours ago are actually tents - they are on the site of old buildings or
nearby, but are a completely different outline. I've done a search on
the wiki, but nobody seems to have been mentioning tagging them before -
I've tagged mine 'building=tent' until someone comes up with a better
scheme.

Hello All,
Greetings from Manila.
As efforts to alleviate the damages from Typhoon Haiyan / Yolanda in
the Philippines shift from response to recovery the need for detailed,
precise information about damages and recovery rates has become more
pressing. Agencies are still investing lots in mass-distribution style
emergency shelter relief but are already looking at the next stage of
"supporting self-recovery" activities and the eventual move towards
permanent shelter solutions.
One of the more affected municipalities in Haiyan's path is Carles, on
the Northeastern tip of Panay Island. Much like the islands of
neighboring municipality Estancia to the south, the exposed islands of
Carles and the buildings along its shores were hit hard by the
typhoon. Survivors are doing an inspiring job of putting their lives
in order and moving on but the need for assistance and support is
still real. We've create a task to support this process at:
http://tasks.hotosm.org/job/392
To support that assistance process we'd like to assess the damages at
a building-by-building level. Our hope is to better target assistance
from aid agencies in the area, track reconstruction progress at a
building level and verify the accuracy of these assessments through
OSM for future work.
Thanks to the continued generosity of the U.S. State Department, we've
been able to procure post-disaster imagery for the municipality of
Carles on the northeast tip of Panay Island. Please download the
imagery into your editing software of choice and be sure to insert the
necessary tags to recognize the NextView license's part in the data so
created.
Many thanks to all of you for your contributions and continued
support. I cannot speak enough to how well received OSM is by
government, NGOs and companies alike here. This operation represents a
huge leap forward in terms of the credibility and recognition of OSM
for disaster response purposes.
Best,
Robert
