Digital Elevation Data ChallengeLIght Detection And Ranging-with Chris Crosby • Airborne scanning laser

rangefinder• Differential GPS• Inertial Navigation

System

30,000 points per second at ~15 cm accuracy

Extensive filtering to remove tree canopy (virtual deforestation)

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)


ASTER level-1B data have had system radiometric corrections and geometric coefficients applied and are reprojected to a given map projection.

2300 “granules” available


Connection Method• ArcIMS, Java Servlet, Manager

Program, Java Implemented Server


Java Servlet – Welcome Screen

Display information to user and communicates with the Manager program, relaying relevant information


Manager ProgramPasses the request onto the next available server (running on GEON Node at ASU)

GEON grid nodes (4 Tb + 10 processors @ASU)


Java Servlet - Results Screen

Display results of IDL processing to user and offer for download processed information (thumbnail and larger *.jpg; *.tar.gz contains full and 8x reduced GEOTIFF [*.tif and *.tfw])
