Frequently-asked questions:


What does this data set describe?

Title:
Idaho GAP Predicted Habitat - AMAJF04010, American badger, Taxidea taxus

Abstract:
The Idaho Cooperative Fish and Wildlife Research Unit's Landscape Dynamics Lab created the wildlife habitat relationship (whr) models for 379 terrestrial vertebrates that regularly breed in Idaho.  Habitat associations for each species were determined by literature searches and expert opinion.  These features were then selected from the following spatial datasets where appropriate: Idaho Land Cover, Idaho Digital Elevation Model, Idaho Climate Zones, and Distance to Hydrologic Features.  The resulting maps were then restricted to the areas where the species had been observed (determined by occurrence within 635 sq. km hexagons.  Each model was reviewed and edited as needed.  Models are stored as geo-referenced image files (.tif and .tfw).  In ARC/INFO, use the IMAGEGRID command to convert the image into a grid.

    Data were downloaded from the Landscape Dynamics Lab Web site.
    
    The original image could not be accessed in ArcGIS due to issues with the G4 compression.  Therefore, the compression format was changed from G4 to LZW using the IMAGEGRID and GRIDIMAGE commands using Arc Workstation 9.1.
    
    IMAGEGRID %prefix%.TIF %prefix%g # # NEAREST DEFAULT
    GRIDIMAGE %prefix%g colormapfile.clr whr%prefix%_id_icfwru.tif TIFF LZW

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Wildlife lists gathered from 62 special management areas across Idaho were used to assess the accuracy of the WHR models.  Only 353 of the 379 species modeled were included in the accuracy assessment due to lack of independent data.  See the Idaho GAP Analysis Report for more information.

  2. How accurate are the geographic locations?

    Unknown

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    All cells within Idaho boundary are assigned as suitable or unsuitable habitat for this species.

  5. How consistent are the relationships among the observations, including topology?

    Not applicable for raster data.
