At this point we have to organize the data collection. Blocks roads, we need to establish a way to collect from various sources and update the info.
Jean-Guilhem Cailton started to organize a few hours a go a Skype group to discuss about routing. It would be good that groups that have the capacity to gather infos about road conditions take contact with us. I read that WFP is to make road damage assessment. These infos could be very useful.

So I'm pouring over this information. I guess what I'm missing - what should I look for to determine how roads, airfields, etc. have been affected by the earthquake and aftershocks? I work for logisticians, so they're curious how they would move stuff (air/land/waterways).
A more precise answer is that we don't have that level of information yet (particularly blocked roads/etc); but as new imagery and others in the field become available it will start to be collected.
Priorities tend to be road network first, followed by buildings; residential areas, etc and other requests by organizations on the ground.
I think we've been requested this time to cover some potential helicopter landing sites, though it's unclear how effective that is (past activations have captured this, but some have been overgrown, etc by the time people got there - uh, anyone with a less anecdotal recollection of this, please chime in!).
A good way to preview some of the data is a tool called "overpass turbo".
Some quick examples:http://overpass-turbo.eu/s/91y - landuse=residential
http://overpass-turbo.eu/s/91z - amenity=hospital
http://overpass-turbo.eu/s/91A - amenity=fuel (gas station most of the time)
http://overpass-turbo.eu/s/91B - aeroways (airfields, helipads, etc)
This gives you a preview of what can be done in heavier weight tools with full data dumps; and the "wizard" makes it fairly easy to query/export/etc.
To help work out what kinds of tags you want to look for beyond the stuff mentioned in the wiki:https://taginfo.openstreetmap.org/
In terms of damage to those facilities, http://kathmandulivinglabs.org/earthquake/main may be the best bet for getting reports; though it won't necessarily focus on the specifics places you are interested in.
