1. Workshop on the ‘Role of Crisis Informatics in Disaster Management: The Case of Nepal Earthquake’
Kahtmandu, August 9 2015
Pierre Béland, Humanitarian OpenStreetMap Volunteer
Coordinator, HOT/OSM Activations
OpenstreetMap Response - 2015 Nepal Earthquake

2. 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

3. OpenstreetMap Response - 2015 Nepal Earthquake
● 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

● Various specialists
Coordination of the mapping response

5. OpenstreetMap Response - 2015 Nepal Earthquake
● 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 images of Kathmandu
valley were cloud free . 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

Pre-Disaster
Kathmandu 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)

Prior to the earthquake, the Nepal OSM community added 48,000 km of roads. From Apr.25, the
international OSM community and various support groups contributed adding an other 60,000 km
to trace unclassified roads, tracks and paths in the remote areas.

20. OpenstreetMap Response - 2015 Nepal Earthquake
● 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
simultaneous contribution of hundred of people
● 17 millions objects edited in 6 weeks – more then for
one year of Ebola response
Observations / Lessons learned

21. OpenstreetMap Response - 2015 Nepal Earthquake
● Media coverage and organization of various mapathon brought an
unprecedented number of new / unexperienced contributors
● Imagery / Tasks monitoring tools should be enhanced to support
major Responses
● Validation problems where often mentionned. Follow-up of
Mapathons and Adapted Learning material to develop
● 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 comparisons.
