3. Background: Earth observation satellite data Releasing the satellite images with a new method on the Internet. Earth observation data for use and dissemination on the web.

4. Background: Aqua/AMSR-E Launched by Delta II rocket on May 4, 2002 Visualizing the Earth observation data obtained from AMSR-E. Creating Web pages to distribute the satellite images to users.

5. “Earth on Web3D (EORC/NASDA)” http://sharaku.eorc.nasda.go.jp/AMSR/3d_amsre/ Web3D/VRML Concepts of the Web contents Background: 1.Earth observation data for both researchers and general users. 2.Educate general users much more about Earth observation. 3.Interesting and easy accessible contents. More interesting contents in the education about Earth observation.

6. What is the Web3D/VRML? Web3D : is a standard of describing 3D objects and interactive environments over the web. VRML : was born as a file format standard among other Web3D technologies in 1994. : is a text language for describing 3D objects. : is simple and light. Web3D/VRML:

7. Simple text language : easy to construct with a text editor. : no need to assemble or compile. Light volume of data : available in low-bandwidth connections. Technical establishment : choice of many plug-ins Advantages of VRML: Is VRML better than other Web3D? Text editor VRML content

8. Aqua/AMSR-E on Web3D: Earth observation data: Sea Surface Temperature and Color Composite (pasted on the spheroid) Sea Surface TemperatureColor Composite Image

9. Aqua/AMSR-E on Web3D: Earth observation data: Sea Surface Temperature and Color Composite (pasted on the spheroids) Parallel Display

10. Aqua/AMSR-E on Web3D: Other contents: Aqua Satellite and Orbit image Aqua SatelliteOrbit Image

11. ADEOS-II on Web3D: ADEOS-II Launched by H-IIA rocket on December 14, 2002 AMSR (Advanced Microwave Scanning Radiometer) GLI (Global Imager) Onboard Sensors:

12. ADEOS-II on Web3D: Expectable observation data: AMSR Sea Surface Temperature Sea Surface Wind/Speed Precipitation Sea Ice Distribution GLI Chlorophyll Concentration Dissolved Organic Material Surface Temperatures Vegetation Cloud Ice Snow Ice

13. ADEOS-II on Web3D: Automatic-Upgrade Program Features of “ADEOS-II on Web3D” Server New Data VRML Files Users JPEG images transmitted to a server, the information is registered, and then VRML files are automatically created on the server side.

14. Conclusion: Earth observation data is not only for researchers, but also general users. → Every data shall be opened up for everyone. Web contents are standing up at the turning point. → Web3D/VRML is effective as solution. Capability of VRML’s expression is still in the high level. → Especially effective in the educational environments.
