Geospatial Information Authority of Japan State Of The Map 2012 September 6th – 8th, 2012 Tokyo, Japan GSI’s Activities for Geospatial Information Applica tions Hiroshi Murakami Director-General of Geospatial Information Department Geospatial Information Authority of Japan (GSI)
Overview 1. GSI and its Mission 2. Programs 3. Digital Map Products and Services 4. Potential Cooperation with VGI Initiatives
1. GSI and its Mission • 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.
1. GSI and its Mission • 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%)
1. GSI and its Mission 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.
2. Programs Geodetic Survey VLBI Observations Horizontal Datum Tide Observations Vertical Datum
2. Programs Geodetic Survey N. American Plate Eurasian Plate Pacific Ocean Plate GNSS-based Control Station Philippine Plate 2 cm/yr
2. Programs National Mapping Maintaining topographic maps at multiple scales: 1:5M, 1: 1M. 1: 200K, and 1:25K (Whole country) >=1:2.5K ((Urban areas)
2. Programs 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)
3. Digital Map Products and Services 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)
3. Digital Map Products and Services Primary Products (ii) Digital Map (National Fundamental Data) Contents: FGD + Additional geospatial features Distribution: Online download or DVD (Vector data) (ii ) Digital Topographic Map 25000 Contents: FGD + Additional geospatial features Distribution: Online download (PDF)
3. Digital Map Products and Services Web Map Service of GSI
3. Digital Map Products and Services Geospatial data overlaid on Web Map
3. Digital Map Products and Services Web map site developed by local governments
3. Digital Map Products and Services Applications that read GSI web map via the Internet
3. Digital Map Products and Services New version of Web map service that has better compatibility with the others and new map design
4. Potential Cooperation with VGI Initiatives 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
4. Potential Cooperation with VGI Initiatives 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
Passable/closed roads Car Movement tracked by Auto Makers Passable Roads Closed Road Information provided by Government
4. Potential Cooperation with VGI Initiatives 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.
4. Potential Cooperation with VGI Initiatives 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.
4. Potential Cooperation with VGI Initiatives 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?
4. Potential Cooperation with VGI Initiatives Summary • GSI acknowledges important roles VGI wil 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.
