[HOT] Tagging scheme for damaged buildings

Would it be useful to partners on the ground if we set up a
Maproulette-type thing to quickly compare post-storm imagery to the
pre-storm structures we've mapped? It might go faster that way, and it
seems to draw lots of participation.
One downside is that it might be tough to guarantee the needed horizontal
accuracy to match a building with a particular pile of rubble.

Hi,
Of course, you are right, this is an emergency, and what is needed first
to deliver aid is to know where people live and how to get there
(buildings can be useful later for more accurate assessments). This
agrees with what has been said on this list before by Maning, who is
very active in the Philippine OSM community, and by others.
And also, mappers, please remember that ground information about damage
comes in only after places can be reached, so it is not because it is
not heared about a place that it is not affected. On the contrary,
remote places, that are not obvious to reach on the ground, are those
for which maps made from satellite view could be the most useful.
Thank you for contributing.
Best wishes,
Jean-Guilhem

Hi,
Here is a map of typhoon eye track, created by Pierre Lorioux of
CartONG, currently intern at ICRC :

Andrej Verity of OCHA wrote:
"It is a great (simple) map that would help me target my thinking &

and is going to have it posted on the HumanitarianResponse.info website,
and linked from the Virtual OSOCC (where UNDAC coordinates).
Maybe it could also help plan OSM mapping?
(Of course, the severely affected areas are much broader than the
highlighted strip).
Best wishes,
Jean-Guilhem

This map seems to correspond to the reported damages by local media,
although many areas are still inaccessible.
Reports from local media is slowly coming in and it is not very good
news. Some reports estimates the death toll to exceed 10K.
While Haiyan/Yolanda is now out of the Philippines, there is new low
pressure brewing in the Pacific [0] which could exacerbate the
situation in many affected areas.
Right now, the Department of Social Welfare and Development (DSWD) the
major government agency organizing the relief is using OSM as the
basemap for its Disaster Situation Map [1].
Please continue working on the current tasks, we will create new tasks
as we get additional request from local responders.
IMO, priorities should focus on:
- access - roads and bridges
- presence of settlements - landuse=residential should be sufficient

PS. I went to Tacloban just this year to talk about FOSS4G and OSM for
DRR. My visit in some ways, sparked the interest of local NGOs, GIS
users and government employees to start contributing to OSM. These
are the areas you may have noticed to be well-mapped road-wise. Some
of these mappers live in the mostly devastated areas. I tried to
contact a few but haven't heard from any of them since the Yolanda
made landfall in Tacloban. Still hoping they are safe.

Hello again HOTties.
So far we have been tracing very large numbers of buildings in the
affected areas. All of the tracing at this point though has been done
through 'pre-disaster' imagery. It is possible that over the next few
days post disaster imagery showing damaged buildings will become
available.
If we do get access to this kind of imagery, it would be good to
already have a tagging scheme in place for marking damaged, destroyed,
or undamaged buildings. This would allow us to very quickly go
through the buildings we have traced and assign each one a tag based
on its conditon.
I would like to know if such a tagging scheme already exists and if it
is documented somewhere. If such a scheme does not exist then we
should look into trying to come up with something to do so.
Also, it would be good to try to show this damage info on the HDM map
rendering if that is possible.

Andrew,
Not much documentation - but during the CO fires we used
building=damaged/destroyed. Would be happy to help make something more
official.

Hi,
You may find something interesting on TagInfo
damage_status seems to be the most used. (Values: intact, damaged)
?
Hope this helps
