The Forest Inventory and Analysis (FIA) program of the USDA Forest Service reports data and information about the Nation's forest resources. Increasingly, users request that FIA data and information be reported and distributed in a geospatial context, and they request access to exact plot locations for their own analyses. However, the FIA program is(More)
W hile investigators have examined the location of biodiversity hotspots in the US (Flather et al. 1998; Chaplin et al. 2000), and the extent to which these areas are protected by the current network of publicly managed lands (Crumpacker et al. 1988; Groves et al. 2000; Scott et al. 2001), far less detailed information has been collected on the geographic(More)
Future climate and land-use changes and growing human populations may reduce the abundance of water resources relative to anthropogenic and ecological needs in the Northeast and Midwest (U.S.). We used output from WaSSI, a water accounting model, to assess potential changes between 2010 and 2060 in (1) anthro-pogenic water stress for watersheds throughout(More)
Large-scale and long-term habitat management plans are needed to maintain the diversity of habitat classes required by wildlife species. Planning efforts would benefit from assessments of potential climate and land-use change effects on habitats. We assessed climate and land-use driven changes in areas of closed-and open-canopy forest across the Northeast(More)
We assessed the consistency across space and time of spatially explicit models of forest presence and biomass in southern Missouri, USA, for adjacent, partially overlapping satellite image Path/Rows, and for coincident satellite images from the same Path/Row acquired in different years. Such consistency in satellite image-based classification and estimation(More)
European settlement of the United States and utilization of forests are inextricably linked. Forest products fueled development, providing the building blocks for railroads, bridges, ships, and homes. Perhaps because of the importance of its forests, the United States has a rich cartographic history documenting its resources. Long-term, broad-scale(More)
BACKGROUND AND PURPOSE Individuals with Parkinson disease (PD) have motor and nonmotor impairments that interfere with exercise participation. The purpose of this study was to examine the feasibility and physical performance outcomes of a community-based indoor tandem cycling program that was designed to facilitate a higher cadence, consistency, and(More)
In this research, we explore the defragmentation of allocated compute resources so as to conserve energy on an IBM Blue Gene/Q. We examine a real trace from a new four-rack system and explore through simulation three heuristics to minimise energy waste through defragmentation. We describe a number of heuristics for detecting when it is desirable from an(More)
—RADARSAT-1 synthetic aperture radar data, speckle reduction, and texture measures provided for separation among forest types within the Twin Cities metropolitan area, MN, USA. The highest transformed divergence values for 16-bit data resulted from speckle filtering while the highest values for 8-bit data resulted from the orthorectified image, before and(More)
