IGU 2013 Kyoto (http://oguchaylab.csis.u-tokyo.ac.jp/IGU2013/index.html), session: GS162-­‐3 Tuesday 06 August,
16:00-­‐17:30, Room555A. The Condition of OpenStreetMap and NeoGeography in Japan

The  Condi*on  of   OpenStreetMap  and   NeoGeography  in  Japan Yuichiro Nishimura*, Nara Women's University Toshikazu Seto, University of Tokyo Taichi Furuhashi, University of Tokyo Haruyuki Seki, Georepublic Japan session:  GS162-­‐3 OpenStreetMap  and  Geographical  Knowledge Tuesday  06  August  16:00-­‐17:30  Room555A

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)

OpenStreetMap  and   NeoGeography • The  project  was  founded  by  Steve   Coast  in  2004.  OpenStreetMap   reached  1  million  registered  users  on   January,  2013.  (hHp:// wiki.openstreetmap.org/wiki/Stats)

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. SotM Tokyo 2012: September, 2012

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.  OSM  and  geographic  educaPon  in  school  and   university

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).

Japanese users • Japanese registered user is about 2,700 in March 2013 (Seto 2013) • The limited number of core users make mach data. http://pushpinosm.org/stats/

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.

Heavy  rainfall  disaster  oin  the  mountainous  area  of   Nara  (Totsukawa,  September  2011 • It takes more than 4.5 hours between Totsukawa village (Nara Pref.) and Nara city by public transport (the distance is about 125km). Totsukawa Nara City © OpenStreetMap contributors, CC-BY-SA

maps  of  Japanese  mountainous  area • relaPvely  low  quality  by  Google  Maps – Google  Japan  uses  zoomed  map  data  by  Zenrin  residenPal  map  mainly   focused  on  the  urban  area. 10

crisis  mapping 11 • Yahoo!  Japan/Alps:  way  data   (imported  in  20th,  Aug.  2011) • Bing  satellite  image  (trace) – mainly  Coastal  area   (Shingu  to  Kushimoto) – no  good  resoluPon  data  in   Totsukawa • GSI  base  map  1:25,000(WMS   trace) – for  drawing  buildings by  heavy  mappers  outside  of  the  local  community

• most of Japanese mappers: male, middle age, "IT lovers" • few proportion of female mappers • few proportion of elderly/ student mappers • few proportion of disability • OSM can helps diverse needs and maps for each users gender/age/ability biases of mappers in Japan

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.

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.

developing  Japanese   rendering  server http://osm.jp/map •rendering  server  fit  to   Japanese  situaPon •more  detailed  scale •Icons  of  convenience   store,  GS  and  other   POI(Point  of  Interests)s. •They  are  helpful  for   the  spaPal   recogniPon  and   navigaPon

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

Japanese GIScience BoK(Body of Knowledge) • mention about NeoGeography • chapter: GIS and society • PPGIS:Public Participation GIS • internet GIS • chapter of GISc education • no mention related to NeoGeography http://curricula.csis.u-tokyo.ac.jp

OSM  training  in  Nara  Women's   University


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

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. http://igugender2013nara.blogspot.jp/p/ accommodation.html
