Fundamental Geospatial Data Preparation Project by GSI

All city planning zone of Japan (approx. 100,000

km2) will be prepared at scales greater than 1:2500

(FY 2007 – 2011)

Other areas were prepared at scale of 1:25000

(FY 2007)

Revision has been started for all city planning zones (approx. 100,000 km2)

at scales greater than 1:2500 (FY 2010～)

(covered about half

area of Japan)

・ over 1,200 stations - Average spacing: about 20km

- Received GNSS signals

(every seconds)

- getting real time data via

IP-VPN (except isolated islands)

・ Central analysis center （GSI in Tsukuba）

- correct and delivery data

- routine analysis

Summary

• The importance of geospatial information is fully

recognized in Japan as one of the platform data

for integration of various administrative

information.

• The Basic Act on the Advancement of Utilizing

Geospatial Information enacted in 2007 is aimed

to develop policies concerning the advancement

of utilizing geospatial information, such as

– developing Fundamental Geospatial Data

– providing sampling data from over 1,200 GNSS-based

control observation stations

– providing tile-based web mapping service
