Using the Landsat 7 enhanced thematic mapper tasseled cap transformation to extract shoreline
J.W. Scott Jr.
2003, Open-File Report 2003-272
A semiautomated method for objectively interpreting and extracting the land-water interface has been devised and used successfully to generate multiple shoreline data for the test States of Louisiana and Delaware. The method is based on the application of tasseled cap transformation coefficients derived by the EROS Data Center for Landsat...
Extending the Beowulf Cluster to the Desktop
George Hamer, Daniel R. Steinwand
2003, Open-File Report 2003-432
Existing Beowulf clusters are normally limited to the actual number of compute nodes physically connected to the cluster's network switch. At some point, it may become necessary to extend the size of the cluster beyond the capacity of the switch. By using existing computers on a campus network, one can extend...

Processing large remote sensing image data sets on Beowulf clusters
Daniel R. Steinwand, Brian Maddox, Tim Beckmann, Gail Schmidt
2003, Open-File Report 2003-216
High-performance computing is often concerned with the speed at which floating- point calculations can be performed. The architectures of many parallel computers and/or their network topologies are based on these investigations. Often, benchmarks resulting from these investigations are compiled with little regard to how a large dataset would move about...
