2. OpenStreetMap
and
NeoGeography
•OpenStreetMap(OSM:hHp://
www.openstreetmap.org)
is
well
known
‘wiki’
like
mapping
project
making
open
geospaPal
data
•Such
collaboraPve
mapping
is
performed
by
NeoGeographers
who
is
not
professional
but
with
voluntary
cooperaPon
(Goodchild,
2007)

3. OpenStreetMap
and
NeoGeography
• The
project
was
founded
by
Steve
Coast
in
2004.
OpenStreetMap
reached
1
million
registered
users
on
January,
2013.

4. OpenStreetMap
in
Japan
•In
recent
years
such
pracPces
also
became
popular
in
Japan.
People
comes
to
recognize
the
problems
of
proprietary
based
geospaPal
data
when
they
using
map
as
the
disaster
situaPon,
mapping
for
the
disability
and
the
community.

5. OpenStreetMap
and
Japanese
Geography
•
The
authors
discuss
the
relaPonship
between
OpenStreetMap
and
Japanese
Geography
from
several
viewpoints.
•1.
The
socio-­‐poliPcal
geography
of
OSM
in
Japan.
•2.
The
limitaPon
and
the
situatedness
of
OSM
•3.

geographic
educaPon

school
and
university

6. 1.
the
socio-­‐poliPcal
geography
of
OSM
in
Japan
• OSM
is
the
boHom-­‐up,
alternaPve-­‐mapping
project.
OSM
o[en
related
to
the
counter-­‐
mapping
acPvity.
• Counter-­‐mapping
is
designed
to
increase
the
power
of
people
living
in
a
mapped
area
to
control
the
representaPons
of
themselves
(Peluso,
1995).
• Local,
boHom-­‐up
type
of
mapping
by
OSM
can
be
seen
to
one
type
of
counter-­‐mapping
(Elwood,
Goodchild
and
Sui
2011).

7. Japanese users
• Japanese
registered user
is about 2,700
in March 2013
(Seto 2013)
• The limited
number of core
users make
mach data.

8. Japanese users
(Seto 2013)
The number of active user editing way data by prefecture
• The active user
and data are
concentrated to
metropolitan
areas and
disaster area in
tohoku-region.

9. Heavy

2011
• It takes more than 4.5

13. Japanese
Neo-­‐liberalism
and
OSM
•OSM
could
be
related
to
Japanese
Neo-­‐liberalism.
Recent
Japanese
‘New
Public
Commons’
could
be
associated
with
such
NeoGeographical
pracPces.
The
openness,
transparency
and
parPcipatory
natures
of
OSM
aHract
aHenPon
by
the
local/
naPonal
government.
•However,
the
public
parPcipaPon
by
using
OSM
has
limited
in
Japanese
poliPcal
situaPon.
The
diverse
needs
expression
by
maps
rarely
adopted
to
the
poliPcal
decision.

14. 2.
the
limitaPon
and
the
situatedness
of
OSM
•The
difference
between
local
mappers
and
global
mappers
should
be
the
problems
in
OSM.
•For
example,
OSM
itself
involve
the
Eurocentrism
such
as
the
place
naming
method
or
the
classificaPon
and
tagging
method
of
the
geographic
features,
which
is
not
fit
to
most
of
Asian
ciPes.

16. 3:
OSM
and
geographic
educaPon
in
school
and
university
•Most
of
the
geographic
educaPon
in
university
and
the
school
is
sPll
old-­‐
fashioned
and
for
educaPng
professionals,
the
new
type
of
mapping
pracPces
like
NeoGeography
are
dissociated
from
it
(Dodge
and
Perkins,
2007) at SotM Tokyo 2012

21. OSM and geographic education
• OSM mapping is quite
meaningful for geographic
education
• how to make map
• how to use GPS
• how to see the place and
geographic features by
fieldwork
• The student also learn the
possibility and the limitation
of NeoGeographical mapping

22. OSM in the university
• The researchers and
lecturers in university
often say to the students
"not to use wikipedia,
because of the no
references or the illigal
copy.
• However, most of them
are careless to the
license and the legal
problems of maps.
• University stuff need to
use open data like OSM.
