Looking back at this first week, the various imagery provides and the OSM contributors have made made a tremendous effort. We have been able to cover the priority zones affected by the earthbreake, to add routes, residential areas. We are updating place names and look to facilitate heliocopters landing.
Did not have time to look closely at statistics. We talk of some three or four thousand contributors. I estimate the edits to be more then 6 millions for the first week (stat to validate when more time).
But after 8 days, people in remote villages are still isolated. There are landslides, road blockages. Also many remote villages like the famous trek routes are only accessible by foot.
We coordinate, work closely with UN agencies, satellite imagery companies, humanitarian organizations. For the first time we see the imagery actors coordinating with the humnanitarian community, this including UNOSAT, DigitalGlobe, HIU, Google.
Pre-disaster imagery has let us provide some useful operational infos such as residential areas and potential
Post-disaster imagery availability is a problem with the monsoon coming soon. DigitalGlobe, Airbus D&S and Skybox imagery prepared, tiled, and hosted by the Google Crisis Response team, and shown on Google CrisisMap is allowed to be traced in OSM. As you can see, as of today the images available have large zones covered by clouds.
With the monsoon season, we should not expect the situation coming better to this regard. After 8 days, there is still no post-disaster imagery for most of the areas. In this context, we will look if there are other options to get imagery.
Validation / Learning material
With all the new contributors, task validation / traininig material are quite important. We started to look at global validations to detect and correct various problems. It is important that both geometry and the various tags in the database be reliable to support the humanitarians working in this quite challenging context.
With the monsoon and the landslides, I think that this will be essential to work a system to assess road condition. We cannot plan using imagery for this. We need to rely on infos coming from people travelling, to interface with various organizations to better collect this information.
Support in Kathmandu - Kathmandu Living Labs (KLL)
The presence of the OSM community in Nepal has assured that we start this Response with a structured map. Over the last year OSM-Nepal did a great job and added various infos such as the administratve limits. There are also good Infrastructure databases (hospitals, etc). This greatly help to interface with the Nepal government and the various agencies. We should assure that KLL be supported adequately to respond quickly. Thanks you KLL for your effort in such a difficult context.
There are many priorities to manage at the same time, and we need to move quickly to support the vulnerable populations in various areas. We receive a lot of calls for support / collaboration from humanitarians in the field. To be efficient, we need that various groups take responsabilities such as Validation, Routin, Training, Follow-up of contributors and simply report at the end of the day. The Lead coordinators, we cannot follow everything in detail.
I invite again the HOT membership and experimented collaborators to communicate with the activation.at.hotosm.org and propose to participate
Thanks all for your support.
