Mark Feller and Dave Hester participated in the 1st Annual UGLE Modeling Workshop held at the University of California-Santa Barbara (UCSB) on March 13-15, 2000. Objective of the UGLE Workshop was to discuss the Modeling Work Group's results obtained from executing the Deltatron 2.1 Land Cover Model (LCM) as well as the upcoming LCM 3.0 parallel processor software release.

RMMC downloaded the January 2000 release of the LCM source code and compiled the Deltatron 2.1 version on the CRSTL Silicon Graphics Unix server. A library containing Isleta image inputs (i.e., full-resolution: 1166 X 1406 to 1/16th resolution: 72 X 87) was created for executing the Deltatron model. After creating the Isleta data library with the HALFGIF utility, RMMC edited all images for compliance with the LCM 2.1 attribution schema as well as for transportation feature continuity. During the quarter, Mark Feller executed LCM 2.1 coarse, fine, and final calibration processes for the Isleta case study using the 1/16th image inputs. A 2050 urban area and LULC prediction for the Isleta quad was modeled using the 1/16th resolution images. RMMC also completed an Isleta LCM 2.1 coarse calibration using the 1/8th images (145 X 175). Executing the LCM 2.1 version to create a 2050 Isleta prediction using the full-resolution images is planned.

During the quarter, RMMC populated a "standard" Modeling Work Group spreadsheet documenting growth control coefficient values for each LCM 2.1 model execution. In addition, Mark Feller created line graphs of the coefficient values and calibration metrics extracted from the avg.log files for each execution. To illustrate the spatial discrepancies between the contemporary LCM landscape inputs and the predicted LCM landscape output, Maria McCormick generated a 1:24,000-scale Isleta, NM case study graphic.

Mark Feller began configuring a Beowulf PC Cluster (1 server, 8CPU's, 200Mhz) for executing the Deltatron LCM 3.0 version in a parallel-processing environment. During the quarter, the LINUX operating system was installed on the Beowulf PC Cluster.

Dave Hester attended the 9th Annual Rocky Mountain Land Use Institute's (RMLUI) Land Use conference held at the University of Denver Law School. USGS Factsheets describing NMD's Urban Dynamics Research Program, Land Cover Characterization Program, RMMC High-Resolution LULC Mapping activity, and the Front Range Infrastructure Land Characterization investigations were distributed at the RMLUI conference.

Richard Pelltier and Dave Hester revised the RMMC UGLE geographic research web site (http://rockyweb.cr.usgs.gov/html/growth/) to reflect the FY00 modeling activities.

During the quarter, RMMC contributed to the NMD Urban Dynamics Congressional Briefing packet. Materials contributed were historical change images (i.e., Denver, Seattle, and Albuquerque), urban growth posters for backdrop displays, and legislative information on urban sprawl and smart growth ballot initiatives.
