CKANへの空間情報機能拡張実装の試み

  1. 1. Yoichi Kayama CKANへの 空間情報機能拡張 実装の試み
  2. 2. Self introduction  OSGeo.JP Board member  OSGeo.org Charter member  A member of GIS Association of Japan (Also a member of FOSS4G SIG)  A Coordinator of QGIS Japanese translation team  GIS Programer and Researcher at Aeroasahi Crporation Twitter ID @pokopen  A member of Association for Promotion of Infrastructure Geospatial Information Distribution
  3. 3. 2013 G8 has announced the Open Data Charter
  4. 4. Governments of many countries began to publish data on the Internet in response to this charter
  5. 5. https://data.gov.uk/
  6. 6. https://www.data.gov/
  7. 7. The government of Japan also began to make the data public site
  8. 8. But
  9. 9. Functions, such as to preview the spatial data in the map in these the Japanese government of the site was not implemented
  10. 10. The Japanese government is promoting a project to utilization of digital spatial information in parallel with the open data
  11. 11. http://www.cas.go.jp/jp/seisaku/sokuitiri/yosan/h26_gsuishin.pdf Spatial information related project budget of the Japanese government (2013-2020)
  12. 12. An overview of the plan of the government related to the spatial information Launch an organization to operate it by creating a foundation system of spatial information Construction of Disaster Prevention System Improve the use of IT in agriculture, forestry and fisheries Activate the local activities To expand the project that uses spatial information technology abroad
  13. 13. I described in this presentation about the marked project in the following red rectangle Launch an organization to operate it by creating a foundation system of spatial information Construction of Disaster Prevention System Improve the use of IT in agriculture, forestry and fisheries Activate the local activities To expand the project that uses spatial information technology abroad
  14. 14. 2014-2015 Ministry of Internal Affairs and Communications has developed a system named G space platform
  15. 15. 2014-2015 Ministry of Internal Affairs and Communications has developed a system named G space platform These groups gave the system development work
  16. 16. I did the work of creating mechanisms to use the spatial information in a combination of open source software in this team These groups gave the system development work
  17. 17. This year Ministry of Land, Infrastructure and Transport is preparing for the operation of this system
  18. 18. This year Ministry of Land, Infrastructure and Transport is preparing for the operation of this system AIGID (Assosiation for Promotion of Infrastructure Geospatial Information Distribution) will make the operation of the system
  19. 19. I am also a member of the AIGID. I work for publishing this system in AIGID current. AIGID (Assosiation for Promotion of Infrastructure Geospatial Information Distribution) will make the operation of the system

  21. 21. System configuration CKAN Solr Drupal PostgreSQL PostGIS GeoServer GDAL/OGR Apache Leaflet
  22. 22. Using CKAN as data catalog
  23. 23. Already extensions for some of the spatial data has been implemented in CKAN  ckanext-spatial  ckanext-geoview  recline_view  ckanext-basemaps change basemap of ckanext-spatial to the maps of Geospatial Information Authority of Japan
  24. 24. Our prototype system
  25. 25. Functions that we have extended  Improved the preview function of spatial resources  Implementation of the spatial data processing functions using the GDAL / OGR  Implementation of the WEB Map to overlay displaying selected plural spatial resources in the CKAN  Made the ability to purchase application by selecting the spatial data product with private companies
  26. 26. Improved the preview function of spatial data  Debuged WMS preview  KML, GeoJSON,CZML  Use GSI map as Background map
  27. 27. Implementation of the spatial data processing functions using the GDAL / OGR
  28. 28. Implementation of the spatial data processing functions using the GDAL / OGR Select Spatial resource in CKAN Select Processing method Specify the parameters for the processing Execute processing (GDAL/OGR) stores the result in the WEB public directory of the server Send the results of the URL by e-mail to the user Users download files from a specified URL
  29. 29. Implementation of the WEB Map to overlay displaying selected plural spatial resources in the CKAN
  30. 30. Select spatial resources to display together then open map
  31. 31. Made the ability to purchase application by selecting the spatial data product with private companies  Some of the private companies in Japan have sold the spatial data. Such as satellite image, aerial photos, laser measurement data, car navigation log, and so the position of the mobile phone log ,they sold.  You can find them in our site.You can also make a purchase application of their data
  32. 32. Made the ability to purchase application by selecting the spatial data product with private companies select the data you want to buy adds the selected information to the cart Create estimates
  33. 33. Future plans  We are working and trying to the public of the system this year in November.  It is also a plan to use paid data of the private sector in this system  We are trying to implement a preview and overlay display of data that varies with time
  34. 34. I am a member of the QGIS community
  35. 35. I am a member of the QGIS community I want to a little talk about QGIS
  36. 36. We can use the wonderful plug-in called CKAN browser in QGIS
  37. 37. We can search for CKAN repository from QGIS With this plug-in
  38. 38. The spatial data in the search have been CKAN can be used as a layer of QGIS
  39. 39. I think QGIS is an excellent tool in order to use such data repository
  40. 40. Thank you for your attention
