6. CYBERINFRASTRUCTURE FOR THE GEOSCIENCES www.geongrid.org http://asterweb.jpl.nasa.gov/ Very useful data, but difficult to locate appropriate scenes, acquire, process and manipulate data for many users. So, we built a system to do “on-the-fly” processing and delivery in a variety of useful formats (note that this was just presented at the ESRI User’s conference)

7. CYBERINFRASTRUCTURE FOR THE GEOSCIENCES www.geongrid.org ASTER level-1B data have had system radiometric corrections and geometric coefficients applied and are reprojected to a given map projection. 2300 “granules” available

8. CYBERINFRASTRUCTURE FOR THE GEOSCIENCES www.geongrid.org Connection Method ArcIMS, Java Servlet, Manager Program, Java Implemented Server

9. CYBERINFRASTRUCTURE FOR THE GEOSCIENCES www.geongrid.org Java Servlet – Welcome Screen Display information to user and communicates with the Manager program, relaying relevant information

10. CYBERINFRASTRUCTURE FOR THE GEOSCIENCES www.geongrid.org Manager Program Passes the request onto the next available server (running on GEON Node at ASU) GEON grid nodes (4 Tb + 10 processors @ASU)
