Outline
• 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 support groups.

Case Studies
The Case Study Areas
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

Mapping Party
• 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 Party2012/05/12-13 Second Mapping Party
2012/03/20 First Mapping Party in Kamaishi■Challenges
• Collected detail information from local residents
• Desire to visit many people in Kamaishi
• Contacted over 40 people in fieldwork (using GPS) and introduced OSM editing
• Logistics support by Yokohama-team
2012/05/12-13 Second Mapping Party in Kamaishi■Purpose
• 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

Collected POI in Kamaishi
What kind of the restorationmap feature(s)
• Targeting shops– The name of the
shop– Type of the service– Opening-closing
time– Telephone number
– restart_day– where is it re-
located?
Case Study 2:Ishinomaki (Miyagi Pref.)
2013/04/13 First Mapping Party
2013/04/13 First Mapping Party in Ishinomaki
■Purpose• Where is the restoration ?• What is tourism attractiveness after-disaster ?
■Challenges• Collaboration with the NPO, company & residents• More easy participation of the OpenStreetMap

Conclusions• The Crisis Mapping contributed a vast amount
of geospatial information in the response period.
• 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.
The Version of Ways in the Tohoku region
Issues & Feature Works• The difficulty of the evaluation for restoration
– Not only quantitative analysis– VGI’s voluminous data; citizen’s continuously
motivation• The gap of the IT literacy and GIS skills in the
Tohoku area– The high demands for paper resources yet– Set up the OSM basecamp in Tohoku region
• Supprt place of learning OSM in regional NPO office
