• Purposes & Overview
• Towards the Restoration
– Case Study 1 : Kamaishi (Iwate Pref.)
– Case Study 2 : Ishinomaki (Miyagi. Pref.)
• Issues & Feature Works
Purposes & Overview
• This presentation explores how to collect and
share the local geospatial knowledge that will
contribute to the community reconstruction
after the Earthquake on an ongoing basis.
• Our research mainly targets are Ishinomaki
(Miyagi Pref.) and Kamaishi (Iwate Pref.) cities.
• While these areas were severely damaged by
the tsunami, many of the local residents have
been very active, establishing NPOs and
Why is a restoration map needed ?
• Response to local “Up-to-date” information
• Official guide is so lately for regional restoration processes.
• The possibility of collaboration by volunteers and residents
Paper Based Voluntary Map
(in Ishinomaki since 2011/07)
• A mapping party is where a group of
openstreetmappers and novices descend on an area to
map it exhaustively, usually over a weekend. It's a very
social event where people can meet up and talk
(usually at a pub) in between mapping sessions.
• After the mapping is finished, the participants share
food and drinks, and enjoy themselves. It's a party,
after all! Indeed mapping is not compulsory at a
mapping party. Sometimes it's all about the party!
Case Study 1:
Kamaishi (Iwate Pref.)
2012/03/20 First Mapping Party
2012/05/12-13 Second Mapping Party
2012/03/20 First Mapping Party in Kamaishi
• Collected detail information
from local residents
• Desire to visit many people
• Contacted over 40 people in
fieldwork (using GPS) and
introduced OSM editing
• Logistics support by

• What kind of restoration map?
• Discussion of the map’s features:
shops, public facilities, tourism resources, etc.
• The development of pdf and/or paper-based self-
making restoration map using OSM data
What kind of the restoration
• Targeting shops

• What is tourism attractiveness after-disaster ?
• Collaboration with the NPO, company & residents
• More easy participation of the OpenStreetMap

• The Crisis Mapping contributed a vast amount
of geospatial information in the response
• The feature related to the restoration is wide
variety form. It is necessary to understand the
space-time in its entirety are various kinds.
• The activities of mapping party in which the
local residents made new maps through the
fieldwork & communication.
Issues & Feature Works
• The difficulty of the evaluation for restoration
–Not only quantitative analysis
–VGI’s voluminous data; citizen’s continuously
• The gap of the IT literacy and GIS skills in the
–The high demands for paper resources yet
–Set up the OSM basecamp in Tohoku region
• Supprt place of learning OSM in regional NPO
