Problem

1. Japanese Spatial Data Infrastructure InitiativesShin-ichi Sobuesobue.shinichi@nasda.go.jpNational Space Development Agency of JapanEarth Observation Planning Department

2. Problem • Scattering data archive and dissemination • Earth observation satellite data archive and dissemination by government (STA/NASDA & EA & MITI) + private sector (Mitsubishi, Hitachi, IMI/NTT-D) • DEM data archive and dissemination by GSI / MOC • Other GIS related data archive and dissemination by national / local government / Private sectors (aerial photo companies, VAR)

3. Problem Points • Standard • No standard for metadata, data format?, etc... • Data policy • Commercialization • Needs • Aerial photo is enough for Japanese GIS • Do we really need EO satellite data to GIS??? • For spatial small country with fine high resolution DEM by GSI (1/1, 000)

4. Standards • Metadata • No activity to coordinate between STA/NASDA and other entities including private sectors yet. • Different interest of data • Data Format • CEOS Superstructure and/or HDF is not adopted by private sectors although public agencies adopt

5. Data Policy • Pricing • Data quality • Calibration / Validation

7. Advanced Land Observing Satellite (ALOS) Main Characteristics Mass 3.9 tons Orbit Sun-synchronous Subrecurrent Altitude 800km Mission Period 2002-2006 Observing Sensors Panchromatic Remote sensing Instrument for Stereo Mapping (PRISM) Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) Phased Array type L-band Synthetic Aperture Radar (PALSAR)

8. ALOS Launch Mass : ~4 t Altitude : ~691.65 km Inclination : ~98.16 deg. (Sun-synchronous Sub-recurrent) Repeat cycle : 46 days, (Sub cycle 2 days) Power : ~7KW Attitude Control : 3 Axis Zero-momentum Attitude Determination Accuracy : 2.0 * 10-4 deg Potion Determination Accuracy : 1 m Data Rate :240Mbps (DRTS) / 120Mbps (DT) Mission Life : 3-5 years Data Transmission : Via DRTS (primary) PALSAR is developed jointly between JAROS and NASDA ADEOS/AVNIR PRISM (simulated data) JERS-1/SAR

9. NASDA ALOS Data Policy …Law/Resolution • NASDA Law • UN Remote Sensing Principles • Fundamental Policy for Japan’s Space Activities (1996) • Space Development Plan (annual) …National Plans • Program of the Office of Earth Observation • Systems • - Three Main goals - • (1) Contribution to Earth Science • (2) Promotion of Practical Use • (3) Technology Development …NASDA Plans …NASDA Data Policy • ALOS Data Policy

11. NASDA ALOS Data PolicyPrinciples • Open and non-discriminatory access to data; • Data use exclusively for peaceful purposes; • No more than cost of reproduction for all data issued from NASDA(Royalty will be charged for commercially distributed data).

12. NASDA ALOS Data Policy Pricing Policy • Open data on the web (limited data: catalog data, disaster, public relations) • NASDA internal use (including PIs) • Research and Public Use = Cost of reproduction • Other General Purposes (distributed by a Distributor) = Data will be provided from NASDA to the Distributor at cost of reproduction and royalty (approx. 10%) → Customer Price will be determined by the Distributor

13. GIS implementation • Governmental initiative • Inter-ministry committee for GIS • Long term plan to implement national spatial data infrastructure and promotion of GIS • Standardization of national spatial data infrastructure and implementation plan • 96-98 : Development of infrastructure • 98-00 : Promotion of GIS (data exchange, policy of inter-use of GIS) • ISO/TC211 national meeting • Spatial Data Standardization Committee

14. GIS implementation • Government Initiative (2/2) • Administrative information promotion plan • Development of on-line system for administrative information • Implementation plan for national spatial data information system (1/2,500 for urban area, 1/25,000 for national level from JFY2000) • Joint effort between public and government • NSDIPA (National Spatial Data Infrastructure Promotion Association)

15. GIS related activity in Japan • ISCGM by GSI • Global mapping projects by satellite data • DEM • Next Generation GIS R & D by MITI • Clearing House (prototype) for SDI by NLA/MOC & MHA • OpenGIS participation • Only companies (NTT, KDD, Hitachi, etc.)

16. ALOS for GIS • Joint Research • With GSI • to create Asia Pacific DEM by using ALOS PRISM • With EA • to create seasonal vegetation map of Japan • Pilot Projects with local government • Gunma, Hokkaido, Fukuoka, Okinawa, etc. • International Pilot Projects • Thailand, Indonesia • GIS for agriculture
