   OSM  “Notes”  （地図メモ）
   • Notes  is  a  core  feature  
   of  the  
   OpenStreetMap.org  
   website  for  placing  
   shared  notes  on  the  
   map  to  assist  in  
   mapping/editing  
   OpenStreetMap.
   • Notes  allow  for  two  
   way  communication,  
   with  the  ability  for  a  
   mapper  to  ask  for  more  
   details  if  necessary.  
   • Since  24th  April,  2013.

    Findings  and  Issues
    • A  lot  of  Notes  find  major  cities  such  as  Tokyo  
    and  Osaka  with  are  also  in  Hokkaido  and  
    Ishikawa  prefectures.
    • However,  many  of  the  users  were  “anonymous”.  
    and  there  was  a  tendency  to  post  bugs  by  
    MAPS.ME  and  Facebook.
    • The  user  interaction  (Notes  version)  between  
    the  OSM  mappers  are  still  in  a  small.
    • To  develop  a  method  to  extract  “Closed”  
    Notes.  Used  for  analysis  of  GIS  data  and  
    resolution  period.
    • It  is  necessary  to  analyze  the  contents  of  
    the  text  deeply  (text  mining  etc.).
