There are still discussions with various NGO's about moving to activation, but
no decision has been taken at this point.
From official reports of casualties, we have identified three valleys where
important lanslides andd casualties are reported. For these valleys, we invite
the HOT and India contributors to map in detail, the roads, waterways and
buildings. When no place tags identify a village, you simply add a
place=village or hamlet tag. For village we do not know the name, we do not add
a name tag.
Below, we identify when possible the valleys by the road no., which should help
to locate them.
When you upload to the OSM database, you are asked to add a comment. To
facilitate the follow-up of mapping, indicate :

Dear Hotties,
I've been periodically (every 3-6 months or so for 3 year) been posting in
crisis mappers and HOT about using UAVs for mapping and other stuff. I'm
really happy you guys are now talking about it!
I've been looking at low-cost UAVs for a while now, and I think that
technology has reached the maturity whereby we can instrument a rig with
sensors for a total cost of less than 5 thousand dollars. Which means we
can basically start shipping these to wherever VERY cheaply, with a HUGE
impact! This is the state of technology TODAY imho.
I'm immensely keen to contribute in substance to a white paper, a focus
group and so on. And I'm even more keen to start actually fundraising,
buying and instrumenting these in my back yard, at the lab or wherever, and
to start shipping these to groups that can use them. I know a couple, and
I'm sure you guys know of more that could use something like this.
Civilian-led high-res imagery for civilian-initiatives : it's the crowd
watching over itself - we're already here! Let's make this happen. Kindly
consider me a ressource for however you're deciding to run with this. But
let's run with this most definitely!
Warm Regards,
-Joseph.

The translation of the two documents posted has now been completed and the
results sent back to Togo. Thank you to Tom Taylor for his work
translating the documents.

Over the last several months, we have mapped all the schools and health
facilities here in Kathmandu, Nepal mostly visiting the ground with GPS.
We, OSM Nepal Community, are now experiencing imagery offset error in the
new Bing images (updated from 2/22/2011 to 11/22/2012) in Kathmandu,
Capital of Nepal (27.699080 lat, 85.317337 lon) leading to positional
displacement of all the mapped features. Although image offsets vary with
places and terrain, the offset we now see seems to be beyond the acceptable
limits. Could the new image be aligned to the existing data?
Further, previous image had a bluish shade and was easier to identify
features on image. The new imagery have greenish haze making it more
difficult to identify features even to expert mappers. Can this issue be
addressed as well?
The Bing Imagery has been updated recently, just a few days ago we believe.

Hi Amrit,
here in Norway we are well acquainted with poorly positioned Bing imagery.
And similarly to Nepal (I presume) this is a big problem in areas where the
elevation shifts frequently over short distances (in other words where it
isn't just flat). It seems Bing isn't really adjusting their imagery to a
digital elevation model. I have complained through Steve Coast who works at
Microsoft/Bing and knows who to contact, but it does not seem to have
helped. I'm hoping Mapbox will come to the rescue...
