Outline of Mutual Utilization System (2/2)
• What is the Mutual Utilization System?– System for mutual communication and integrated data utilization
by connecting various databases of Earth observation data with each other on line and with standard interface (ensuring compatibility of meta data, data, communication protocol, etc.)

Access to the Mutual Utilization System
Benefits of Adoption of Standard I/F
Various databases can easily connect and collaborate with each other
Adoption of Standard I/F
Users can enjoy active handling such as expansion/reduction, superimposing, thematic map generation with only browser instead of special applications for experts.
Users can utilize satellite data in combination with other data
Satellite data becomes more attractive and more utilized

Function structure of prototype system
Users will view various satellite images, maps, and statistic chart as seamless information through the prototype system as follows:
1. in global scale (especially Asia region)
* superimposed display with the border, other division line* images: global true color mosaic image, global precipitation, global sea surface temperature (SST), etc.
2. in the scale of nation * superimposed display with topography map, population statistic mesh, etc.
* images: satellite image of all Japan (250 m mesh)3. in local scale (around their residence) * superimposed display with administration map data Gifu Prefecture’s “furusato” (hometown) GIS center, Okinawa Prefecture’s GFSS, Fujisawa City’s GIS Portal, etc. * background: true color image, land utilization classification map, temperature map, etc. * superimposed display of basic map (population statistics, topography map, etc.) and disaster related data * superimposed display with environment data (vegetation map, animal survey map, etc.)4. to view topics contents * updating the latest images generated by JAXA for public relations.

Summary: Prototype construction and study on mutual utilization system (1/2)
Achievement in FY 2003 (until March 2004):* Prototype of satellite data mutual utilization system was
constructed in various fields according to each utilization scenario in cooperation with MAFFIN, Chiba University and Keio University.
* Mutual connection among plural organizations was performed and the availability of the standard I/F was confirmed.
Plan for FY2004:* To continue evaluation of prototype system and to enrich data contents
* To modify and tune up the prototype to construct final system by clearing actions.
* To make utilization scenario such as how to select distributed data, how users utilize the data.
Summary: Prototype construction and study on mutual utilization system (2/2)
Items to be noticed– Close cooperation with other activities is needed.
–Digital Asia Network (Data utilization expansion in Asia as a prototype) –CEOS / WGISS ( Mutual utilization with the other space agencies’ databases )–WSSD follow-up type 2 ( GIS system construction)–ISO/TC211 and OGC
– Consideration of Data Policy on charging system is needed
– Standardization has not been completed yet especially on satellite data.
– Clarification of meaning of each satellite data and other data is needed
– Careful handling and careful interpretation about integrated data are needed.

Status of EarthViewer 3D System in JAXA/EORC
• Finished installation of public server and image processing server in JAXA/EORC
• Preparing contents: High resolution satellite data of urban areas and globally homogeneous mid resolution satellite data
• 10 licenses to install the application into terminals Planning to lend licenses out to science museums and science events/ festivals for general users and children to make familiar with satellite data
