Nepal Earthquake: Report from KLL Situation Room- Day 5 (April 30)

Since we wrote yesterday, our situation room has increased in size, with volunteers working in the parking lot, back yard cafe, and at the Nepali Government’s Health Emergency Operations Center.

Satellite and UAV Imagery

We are still relying on pre-disaster data for much of our map-making. Mapping the roads and houses that were around pre-disaster is extremely important, but there is still an immense need for post-disaster imagery. There has been rain and heavy cloud cover since the earthquake hit which has hampered this effort. We are working with satellite imagery companies who are willing and eager to supply us with imagery, but who are not able to take the imagery at this point. The rain has also made it difficult for those sleeping in tents and for those involved in rescue efforts.

We have provided easy to use AOI (areas of interest) for image acquisition, and now we just wait for better weather so that Satellites can actually take pictures, and help us collect crucial imagery.

Continued mapping

Mapping efforts continue to go strong, seeing a huge increase in the number of mappers who have joined our efforts in the last day. 3500 mappers are actively involved in mapping Nepal, a 1200 person increase from yesterday’s report. Our thanks go out to the HOT-OSM Summit and the over 700 new mappers who have started mapping since yesterday. In our office, volunteers have been mapping Dolakha and Sindhupalchowk, two of the hardest hit districts in this crisis.

Some of the mapping work by HOT Volunteers also made it to the New York Times, which made quite a brilliant graphic of all of the open camps that were spread out around the city.

Getting the Map to Relief Workers

One of the benefits of OpenStreetMap is its open data license, which is leverage by several smartphones which allow access to the map offline. In addition to focusing on improving the map, we spent time today showing relief workers how to use offline maps of all of Nepal. Today, the KLL team was able to program a change so that OSM data is pushed to offline formats all the changes every hour, allowing those with Android phones to download offline maps including OSM data updated the very same day, leveraging all of our volunteer effort.

KLL members were also stationed today at the Nepali Government’s Health Emergency Operations Center to upload OSM and other offline maps on to relief workers phones directly.

Updates

Our casualty and injured map is updated each time the Nepali Government publishes new data, including with the most recently data that was published this morning.

Roughly 100 reports that came in to http://quakemap.org the last evening, and new reports continue to come in. We spent quite a bit of effort today to validate some of the reports on the site, including deleting many duplicate efforts. We are also focusing a lot of our efforts now on getting these reports to those who can follow up on the reports effectively.

In the meantime, a how-to guide was created to show volunteers how to approve and disseminate reports, and new volunteers from Bibeksheel Nepali are being mentored by volunteers from NepalMonitor.org, Parewa Labs and Kathmandu Living Labs.
