What does this data set describe?

Title:
Temperature within the Idaho portion of the LCA; Average Yearly Dew Point (1988, 1989)

Abstract:
These data are spatially gridded Average Yearly Dew Point Temperatures within the Idaho portion of the Landscape Characterization Area (LCA). The coverage was created from data downloaded from the Interior Columbia Basin Ecosystem Management Project (ICBEMP) web site (http://www.icbemp.gov/).

Supplemental information:
Two years of annual attributes have been combined in this cover.  1988 represents a dry year and 1989 represents a normal year.

Geographic Information System (GIS) data layers or themes were compiled or created in support of the ICBEMP Assessment and the development of the Eastside and Upper Columbia River Basin Environmental Impact Statements. The themes were derived from source maps, photos, or transfer media ranging from 1:12,000 to 1:4,000,000 in scale. Some GIS themes mapped features continuously across the entire project area while others covered discrete areas only (e.g. subsample watershed areas). Major data providers included individual administrative units of the Forest Service, Bureau of Land Management, U.S. Fish and Wildlife Service, Environmental Protection Agency, U.S. Geological Survey, U.S. Bureau of Mines, Bonneville Power Administration, universities, state agencies, American Indian tribes, and non-governmental organizations.

The ICBEMP cannot assure the reliability or suitability of this information for a particular purpose.  Original data was compiled from various sources.  Spatial information may not meet National Map Accuracy Standards.  This information may be updated without notification.

    Date: 20000506 (change 2 of 2)
    The grid coverage was imported into ArcInfo.
    
    GRIDASCII was used to create an ASCII file for each year (1988 and 1989).
    
    ASCIIGRID was used to create individual grids for each year in order to project them.
    
    PROJECT was used (Interpolation method: BILINEAR; Out_cellsize: 2000) to project each grid from Albers to Idaho Transverse Mercator (IDTM).
    
    A buffer coverage (buffer_distance 2000 meters) of the LCA coverage was created to use for clipping the grids.
    
    LATTICECLIP was used to clip each projected grid with the LCA buffer coverage.
    
    The GRID function COMBINE was used to create one grid with three attibutes.
    
    This metadata file was created in SMMS using metadata downloaded with the original coverage.
