Research  Trends

Neogeography / Neocartography •  Neogeography is about sharing location information with friends and

visitors, helping to shape contexts, and conveying an understanding through the knowledge of place. (Turner, 2006)

•  “Map makers who may not have come from traditional mapping backgrounds, and are frequently using open data and open source mapping tools ….. Chilton, S. (2008), M.J. Kraak (2011)

Volunteered Geographic Information •  Citizens are using handheld devices to collect geographic information and

contribute it to crowd-sourced data sets; they are employing Web-based mapping interfaces to mark and annotate geographic features…

•  These citizens are largely untrained; their actions are almost always voluntary, and their results may or may not be accurate.

•  However, their activities represent a dramatic innovation that will certainly have profound impacts on GIS.

•  Michael Goodchild (2007): “Citizens as Sensors”

Challenges  Open  Geo  Data  in  Japan •  CreaBng  Open  Geo  Data  

◯ CreaBng  method  are  widely-­‐opened  !  (cf.  github)  △Using  a  geocoder  (address  matching)  is  limited.  

•  DistribuBons  of  Open  Geo  Data  ◯ DisseminaBon  of  the  open  source  placorm  ◯ OpportuniBes  for  applicaBon  development  increase  △Data  related  to  regional  issues  is  less  (cf.  staBsBcs,  white  papers:  most  use  only  point  data)  

•  Effect  and  EvaluaBon  of  Open  Geo  Data    △ Update  of  the  data/community  are  being  conBnuously?
