The document describes the history and growth of OpenStreetMap in Japan, including early mapping activities in 2007-2008. It then discusses the impact of the 2011 Tsunami, including how OSM mappers worked to map the extensive coastal changes. The community saw a surge of activity to provide maps for disaster relief efforts. OSM has since continued growing in Japan with more mappers, data imports, and tools to better support the local community.

63. Personal Thoughts
●
Free services and data donations by large
enterprises
● Making business with natural disasters
● Preparedness for natural disasters
● Duplicate efforts, even competition?
●
How much of our activity really helps or reaches
disaster victims?
SOTM2011 - #63 daniel@osmf.jp

64. Outlook and plans of OSM(F) Japan
● Increase the number of active contributors
● Import the large amount of available data
● OSM tile server with Japanese styled map
● Promote the usage of OSM data in Japan
● Catch up with Germany!

65. 3 main things I have learned in
4 years mapping in Japan
SOTM2011 - #65 daniel@georepublic.de

66. {1}
What you take as granted
in “Western” countries
is likely to be different
somewhere else.
SOTM2011 - #66 daniel@georepublic.de

67. {2}
Language can be a real barrier
SOTM2011 - #67 daniel@georepublic.de

68. {3}
OSM is a great way to make friends
when you're in a foreign country
SOTM2011 - #68 daniel@georepublic.de

69. If you come to Japan, send an email to
http://lists.openstreetmap.org/mailman/listinfo/talk-ja
and some local mappers will help you to get
around!
