Geospatial Information Authority of Japan1. GSI and its Mission

• GSI: Geospatial Information Authority of Japan.– Formerly, Geographical Survey Institute.

• Original body was established in 1869.• Responsible for national surveying and ma

pping including law enforcement of the Survey Act.


• Survey Act:– Standard geodetic datum.– Regulations for surveying and mapping proje

cts conducted by public organizations to ensure the high quality of results and avoid duplicated efforts.

– Licensed surveyor. Public Organizations (80%)

GSI’s Mission

• Facilitate applications of geospatial information through the following activities on surveying and mapping so that the users will find them valuable, and hence contribute to the economic growth and the improvement of the quality of life of the people.– Develop, maintain and distribute fundamental geospati

al information;– Develop an environment that facilitates efficient develo

pment of a variety of geospatial information, and allows anybody to easily use it; and

– Cooperate with both domestic and international bodies.

National Mapping

Maintaining topographic maps at multiple scales:1:5M, 1: 1M. 1: 200K, and 1:25K (Whole country)>=1:2.5K ((Urban areas)


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)

Geospatial Information Authority of Japan3. Digital Map Products and Services

Primary Products(i) Fundamental Geospatial Data (FGD)

Control points,Transportation, Boundaries, Buildings, Waters

Web Map Service of GSI


Geospatial data overlaid on Web Map


Web map site developed by local governments


Applications that readGSI web map via the Internet


New version of Web map service that has better compatibility with the others and new map design

Geospatial Information Authority of Japan4. 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


Past Experiences with Volunteers

• Response to the Great East Japan Earthquake– Volunteer mapping groups– Sinsai.info

– Emergency Map Team

– Passable/closed road information through crowd-sourcing

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.


Cooperation with OSM Foundation Japan

• Dr. Furuhashi, Vice President of OSMF Japan, and his colleagues visited GSI in July and initiated a dialogue to discuss potential 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 benefits and understanding.


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?


Summary

• GSI acknowledges important roles VGI will play for the future in geospatial information applications, as they have been internationally appreciated, and exemplified by the disaster response to the 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 issues.
