  • 1. Geospatial InformationState Of The Map 2012 Authority of JapanSeptember 6th – 8th, 2012Tokyo, Japan GSI’s Activities for Geospatial Information Applica tions Hiroshi Murakami Director-General of Geospatial Information Department Geospatial Information Authority of Japan (GSI)
  • 2. Geospatial InformationOverview Authority of Japan 1. GSI and its Mission 2. Programs 3. Digital Map Products and Services 4. Potential Cooperation with VGI Initiatives
  • 3. Geospatial Information1. GSI and its Mission Authority of Japan • GSI: Geospatial Information Authority of J apan. – Formerly, Geographical Survey Institute. • Original body was established in 1869. • Responsible for national surveying and ma pping including law enforcement of the Sur vey Act.
  • 4. Geospatial Information1. GSI and its Mission Authority of Japan • Survey Act: – Standard geodetic datum. – Regulations for surveying and mapping proje cts conducted by public organizations to ensu re the high quality of results and avoid duplica ted efforts. – Licensed surveyor. Public Organizations (80%) Spending Private Companies GSI (1%) (20%)
  • 5. Geospatial Information1. GSI and its Mission Authority of Japan GSI’s Mission • Facilitate applications of geospatial information th rough the following activities on surveying and m apping so that the users will find them valuable, a nd hence contribute to the economic growth and t he improvement of the quality of life of the peopl e. – Develop, maintain and distribute fundamental geospati al information; – Develop an environment that facilitates efficient develo pment of a variety of geospatial information, and allow s anybody to easily use it; and – Cooperate with both domestic and international bodie s.
  • 6. Geospatial Information2. Programs Authority of Japan Geodetic Survey VLBI Observations Horizontal Datum Tide Observations Vertical Datum
  • 7. Geospatial Information2. Programs Authority of Japan Geodetic Survey N. American Plate Eurasian Plate Pacific Ocean GNSS-based Plate Control Station Philippine Plate 2 cm/yr
  • 8. Geospatial Information2. Programs Authority of Japan National Mapping Maintaining topographic maps at multiple scales: 1:5M, 1: 1M. 1: 200K, and 1:25K (Whole country) >=1:2.5K ((Urban areas)
  • 9. Geospatial Information2. Programs Authority of Japan National Mapping A new legislation in 2007, the NSDI Act, prescribes that the government is to develop an accurate map dataset as the standard reference to the other geospatial information, and make it freely downloadable to the public. Fundamental Geospatial Data (FGD)
  • 10. Geospatial Information3. Digital Map Products and Services Authority of Japan Primary Products(i) Fundamental Geospatial Data (FGD) Control points, Transportation, Boundaries, Buildings, Waters RMSE: =< 2.5m (in urban areas) =< 25 m (outside) Elevation RMSE: =< 1 m (in urban areas) =< 5 m (outside)
  • 11. 3. Digital Map Products and Services Geospatial Information Authority of Japan Primary Products(ii) Digital Map (National Fundamental Data) Contents: FGD + Additional geospatial features Distribution: Online download or DVD (Vector data)(iii) Digital Topographic Map 25000 Contents: FGD + Additional geospatial features Distribution: Online download (PDF)
  • 12. 3. Digital Map Products and Services Geospatial Information Authority of Japan Web Map Service of GSI
  • 13. Geospatial Information3. Digital Map Products and Services Authority of Japan Geospatial data overlaid on Web Map
  • 14. Geospatial Information3. Digital Map Products and Services Authority of Japan Web map site developed by local governments
  • 15. Geospatial Information3. Digital Map Products and Services Authority of Japan Applications that read GSI web map via the Internet
  • 16. Geospatial Information3. Digital Map Products and Services Authority of JapanNew version of Web map servicethat has better compatibility withthe others and new map design
  • 17. Geospatial Information4. Potential Cooperation with VGI Initiatives Authority of Japan Past Experiences with Volunteers • Updates/errors/improvements on maps – Infrequent comments/inputs from map users – “Map Monitors”/“Geo-info Monitors” – Cooperation with climbers group for the latest on mountain trails using GPS loggers Doesn’t exist New trail
  • 18. 4. Potential Cooperation with VGI Initiatives Geospatial Information Authority of Japan Past Experiences with Volunteers • Response to the Great East Japan Earthqu ake – Volunteer mapping groups – Sinsai.info – Emergency Map Team – Passable/closed road information through crow d-sourcing Posted on the web
  • 19. Passable/closed roads Geospatial Information Authority of Japan Car Movement tracked by Auto Makers  Passable Roads Closed Road Information provided by Government
  • 20. 4. Potential Cooperation with VGI Initiatives Geospatial Information Authority of Japan Cooperation with OSM Foundation Japan •GSI created an award program on GIS applications and contents that incorporate GSI data. •24 nonprofit organizations contributed to the program as the nominating bodies by nominating applications and contents for the award. •OSMF Japan volunteered as one of the nominating bodies.
  • 21. Geospatial Information4. Potential Cooperation with VGI Initiatives Authority of Japan Cooperation with OSM Foundation Japan • Dr. Furuhashi, Vice President of OSMF Ja pan, and his colleagues visited GSI in July and initiated a dialogue to discuss potenti al areas of cooperation, including: – Use of GSI’s web map data by OSMF Japan f or change detection; and – Secondary uses of FGD by OSMF Japan. • The dialogue should continue for mutual b enefits and understanding.
  • 22. 4. Potential Cooperation with VGI Initiatives Geospatial Information Authority of Japan Challenges for Further Cooperation (Personal view) • Quality of provided information – Accuracy: positional, temporal, thematic, and topological (Verification needed?) • Homogeneity/sustainability – Inhomogeneous distribution of volunteers? – Any disruption/discontinuation of activities? • Disaster response – Voluntary vs. Preparedness – Pre-disaster exercises? – How can volunteers and governments work to gether?
  • 23. 4. Potential Cooperation with VGI Initiatives Geospatial Information Authority of Japan Summary • GSI acknowledges important roles VGI will play for the future in geospatial information applicatio ns, as they have been internationally appreciate d, and exemplified by the disaster response to t he Haiti earthquake and others. • The dialogue has just started, but many positive outcomes and mutual benefits are envisaged for the future, as we work on some outstanding issu es.
