  5. 5. 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)
  6. 6. 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”

  33. 33. Challenges Open Geo Data in Japan • Creating Open Geo Data ◯Creating method are widely-opened ! (cf. github) △Using a geocoder (address matching) is limited. • Distributions of Open Geo Data ◯Dissemination of the open source platform ◯Opportunities for application development increase △Data related to regional issues is less (cf. statistics, white papers: most use only point data) • Effect and Evaluation of Open Geo Data △Update of the data/community are being continuously? 33
