CKAN is an open source data portal platform that is widely used around the world. It provides features like publishing and managing datasets and metadata, powerful search and API access, support for standards like DCAT, and extensive customization options. CKAN is developed by the Open Knowledge Foundation and a team of developers, with deployments in governments and organizations to make their data accessible and usable.
- The document describes Yoichi Kayama's work extending spatial data functionality to the CKAN open data platform to support the Japanese government's open data and spatial information initiatives.
- Key extensions to CKAN implemented include improving the spatial resource preview function, adding spatial data processing tools using GDAL/OGR, overlay mapping of multiple spatial resources, and enabling purchase of spatial data products from private companies through the system.
- Future plans include public launch of the system in November along with incorporating paid data from private sector vendors.

A Study of the Development and Distribution of Open Geospatial Data in Japane...Toshikazu Seto
?
This document summarizes a study of open geospatial data development and distribution in Japanese local governments. It finds that over 130 local governments have published open data, with the first being Sabae City in 2012. The number of publishing cities increased rapidly from 2014 onward. Geographic data is primarily distributed for disaster prevention, education, and tourism purposes. While the quantity of open data has increased, the formats remain limited. Further development of applications and studies of data characteristics are needed to better support open data distribution.
This document compares the distribution of open geospatial data between cities in Japan and other countries. It finds that while Japanese cities provide a limited number and format of open datasets, including geospatial data, cities in the US and EU tend to provide more open data in various formats through platforms like CKAN. Specifically, US cities using Socrata organize data by format and have a relatively high proportion of RDF and geospatial data. The document calls for future research evaluating data usage and introducing civic applications to better achieve open government goals of citizen participation.
This document summarizes research on how OpenStreetMap (OSM) was used for crisis mapping and community rebuilding efforts in Japan following natural disasters. It provides two case studies: (1) an offline mapping party in Ishinomaki City after the 2011 earthquake to create reconstruction maps with volunteers and residents; and (2) crowdsourcing mapping during and after typhoons in Izu Island Town in 2013 and Hiroshima City in 2014. The research found that OSM activities allowed sharing of up-to-date situation information and suggested such activities could support new forms of community rebuilding. However, OSM remains difficult for beginners, so developing learning materials and paper maps is important to sustain participation. Future work includes open data
This document discusses a study conducted in Japan to collect and utilize real-time geographic information from local government vehicles like snow plows. Researchers equipped vehicles with smartphones running an app to automatically log driving data like location, speed and time. This data was uploaded and visualized online. The study aimed to test using open-source mapping and apps to support local governments. It conducted case studies in two cities, tracking snow plow distances and times. While challenges remained, the goal was to achieve cooperation between governments and residents by making such real-time geographic data more open and accessible.
1) The document discusses open data and open platforms for geospatial information. It provides an overview of the Center for Spatial Information Science and their work in developing spatial databases and promoting joint research.
2) It then covers trends in neogeography, volunteered geographic information, and citizens as sensors. Examples are given of open data projects in Japan that address regional issues through open data and platforms.
3) Challenges of open geospatial data in Japan are discussed, such as limited address geocoding capabilities and lack of regional issue data. The increasing opportunities for application development through open data platforms are also noted.
