OpenStreetMap Response - 2015 Nepal Earthquake

Workshop on the ‘Role of Crisis Informatics in Disaster Management: The Case of Nepal Earthquake’Kahtmandu, August 9 2015

Pierre Béland, Humanitarian OpenStreetMap VolunteerCoordinator, HOT/OSM Activations

OpenstreetMap Response - 2015 Nepal Earthquake


The role of HOT in Disaster Management● Interface between the OSM community and the humanitarian organizations● Flexible coordination with the UN Agencies, international organizations and

GIS teams - We adapt rapidly to the particularity of each region and disaster

Quick response to support the first responders – The BaseMap (road network and villages outline) is the first priority

● Imagery Acquisition, Process Hosting : Support from Imagery providers and HOT volunteers

● Imports,Tutorials. Validations● Define Tasks with partners, monitor progress

Humanitarian OpenStreetMap Team


● Coordination Room via Skype was effective a few hours after the earthquake – a few hundred participants

● Kathmandu Living Labs was operational in the second day of the Response

The Nepal Earthquake Response


● Humanitarian OpenStreetMap Team● Kathmandu Living Labs● UN agencies● International organizations (MSF, Red Cross, etc)● Digital Humanitarian Network● Imagery providers● Organizations involved in Post-Disaster Assessments

- UNOSAT, DigitalGlobe● Various specialists

Coordination of the mapping response


● Pre Disaster : Bing Imagery available for most of the area. HIU provided an image to complete the coverage

● Post-Disaster : Activation by the International Charter – Satellites re-oriented to quickly provide new images

● With the bad meteo of the first week, only a images of Kathmandu valley were acquired. OSM did quickly locate the informal camps from these images.

● Support from DigitalGlobe, AirBus Defence & Space, HIU (US State Department), MapBox, Google

Imagery acquisition, process, hosting


Google CrisisMap to monitor imagery


Pre-DisasterKathmandu valley was already traced by Kathmandu Living Labs

● Day 1 : Highway Network, mountain paths● Day 4 : villages outline, buildings, Helico landing● Day 7 : Place names

Post-disaster● Day 4 : IDP Camps Kathmandu valley (2 days)● Day 11 : IDP camps, damaged villages outside Kathmandu (jobs

progressed slowly and are not completed)

Timeline of the response


● KLL traced Kathmandu years prior to the earthquake

● 04-25 Pre-Disaster Trace roads

● 04-28 Post-Disaster Kathmandu + Banepa IDP Camps

● 04-28 Pre-Disaster Trace Buildings Gorkha, Sindhupalchowk, Dunche, Langtang, etc

● 05-01 Post-Disaster outside Kathmandu → Gorkha

● 05-01 Import place names

Timeline


● Map and route navigation on the web● Map and route navigation Offline on Small Mobile devices● Poster Paper maps to plan activities● Data exports for GIS analysis● Hourly updates of data● Local support plus training by Kathmandu living labs

● Imagery providers reacted quickly and delivered post-disaster imagery daily. But Weather conditions limited access to images of quality

● OSM Maps & Services – A complete solution is available instantly to respond to emergencies

● The HOT Tasking Manager let's coordinate simultaenous contribution of hundred of people

● 17 millions objects edited in 6 weeks – more then for one year of Ebola response

Observations / Lessons learned


● Media coverage and organization of various mapathon brought an unprecedented number of new contributors

● Validation problems where often mentionned. More monitoring tools, follow-up of Mapathons and Adapted Learning material should be developped

● OSM priority is to provide the BaseMap and the Map & Services necessary for the various field teams and GIS specialists.

● A workflow should be developped with the Post-assessment agencies for more complementarity, OSM supporting them primarily with the basemap needed for assessments comparizons.
