{}#yiv7379100801 Pierre, Bill, I can confirm the imagery source is the same.
Meaning, the imagery we licensed openly was used both by HOT (via Mapbox) and
on the Tomnod platform. I am actually putting a blog post together on this
topic, and this thread has been *very insightful*. Barrier of entry is indeed
one of the huge differentiators! As an example, my kids can participate on
Tomnod, but need another decade or so before they can contribute to OSM J. As
such, we are seeing (I believe) a higher volume of contributors via Tomnod:
over 25,000 unique contributors so far. So far, here is what the Tomnod
team has validated, AND, here is a link to the GeoJSON: 488 Damaged
Buildings Verified, 36 Damaged Roads Verified Download the Validated geojson:

Subject: Re: [HOT] TomNod integration for the next time around Hi Pierre,
I think we're already using the same imagery; it's entirely from DigitalGlobe,
and the Mapbox crew processed that and made it available to us within hours of
it being released (Camilla or Charlie - correct me if I'm wrong). The issue is
that participants (~5,000 people this time) in DigitalGlobe's Tomnod project
are deriving basic damage assessment data from the same imagery, and that
information isn't making it to OSM.
The two ideas I outlined below are just sketches for how we could make use of
that derived data to save time and effort, though there are surely many more
possibilities. -Bill On Wed, Apr 29, 2015 at 3:36 PM Pierre Béland

everything. We surely have to coordinate with others and not repeat what
they have done. This imagery would be useful for OSM response to have general
evaluations of villages + roads. We can also provide access to TMS images to
hums and Nepal gov. Monitoring is uneasy with all the imagery requests,
imagery available from various sources. It would help that the image
monitoring uMap be completed with all the tasks and available imageries.

Do we have easy access to these imagery used for evaluation. Do we have tms
link to easily use. Could the info be added to the uMap? regard

Objet : Re: [HOT] TomNod integration for the next time around My bad -
Robert pointed out that I pasted the wrong source data link in there (it was
for TomNod Haiyan). Here's the Nepal data: https://t.co/zzSX2qrelM -Bill

- data: http://mapperdev.tomnod.com/results/ It seems like there might be
an opportunity in future activations (or now) to use this data for: 1.)
Planning and prioritization - as we move into damage assessment we're probably
going to be a step behind the TomNod participants; we should be able to
configure tasks that focus on areas with a high concentration of damage reports
and high levels of agreement. (I can't claim origination of this idea:
https://twitter.com/iheartcrowds/status/593170666662146048) 2.) Direct import -
this is more dangerous, but there's an opportunity to directly link TomNod
contributions to OSM. High-agreement damaged buildings seems like a possible
starting place. There are many technical considerations to be ironed out,
including the realtime nature of the TomNod data. It could benefit from a
streaming API of some sort, as well as some form of integration in the task
manager. In the meantime there's this somewhat-awkward url for overlays:
https://cartocdn-ashbu.global.ssl.fastly.net/geosprocket/api/v1/map/9ec70f30baf2a63e797ae341c8965733:1430273972053.4001/{zoom}/{x}/{y}.png?map_key=dca6cb71991448200cc2ade26ff013da486a78ca&cache_policy=persist
Hopefully this is an opportunity to minimize effort duplication and
leverage another motivated group of contributors. -Bill Morris
