This document discusses the response of OSGeo Japan and other communities to the 2011 Great East Japan Earthquake using open source geospatial tools and crowdsourced mapping. It describes how aerial and satellite imagery was accessed and georeferenced to assess damage. Web mapping services were set up to share this geospatial data with emergency responders. Students and volunteers contributed to OpenStreetMap to map roads, buildings and evacuation centers. Lessons learned include the importance of open source tools and communities for rapid crisis mapping in future disasters.

4. The Great East Japan Earthquake
March 11th, 2011 14:46
M9.0 quake and Tsunami disasters
affected the Tohoku region
and wide area of eastern Japan
About 15,700 died and 4,500 missing
Nuclear power plant crisis
Power failure in wide region
lots of confusions in Tokyo area (communications, transportations)
etc.

13. Georeferencing Aerial Photographs Project
@wata909
Stayed in Germany
• Starting from OSGeoJP-discuss ML
• Over 20 volunteers joined to the project
• About 100 scenes of aerial photographs
were geo-rectified in 2 days
• About some thousands of photographs
were merged by GDAL
• Some related projects were setup
in order to facilitate the works
14. Georeferenced Photo by Volunteers
Iwate, Miyagi and Fukushima Pref.
Georeferencing
using QGIS Georeferencering plugin
15. Georeferenced Photo by Volunteers
Aomori and Iwate Pref.
Task management
using Google docs
16. Various Related Projects

58. Comparing with the Great Hanshin EQ
(Jan. 17th, 1995)
M7.0 quakes hit in Kobe area, more than 6,000 were killed
• Many online voluntary activities, especially geographical
• Internet infra developments and cellphones improvements
• Utilizations of FOSS4G tools
• Many and variety of collaboration works thru network
• Not only domestic activities
but many supports from other countries
59. For faster response to future disasters
• Enhance community bodies
• Roles of communities in emergency situations
• Collaborations with other countries,
• mitigate language barrier
• Promote FOSS4G, the training and preparing documentations
