Frequently-asked questions:

What does this data set describe?

Title:
Digital Orthoimage of the 30 x 30 Minute Tile N41W1121, Idaho Generated from SPOT Satellite Imagery

Abstract: 
The USA Select product is a statewide panchromatic tonal balanced, 30-minute x 30-minute SPOTView product designed to be load-n-go into GIS and image processing systems. The source imagery is SPOT PAN 10-meter data. The most current imagery was preferred. Fall/Winter/Spring (leaf-off) scenes were preferred, but summer (leaf-on) imagery was used if scene gaps were present.

The Idaho Department of Adminstration coordinated the purchase of these data among numerous entities in Idaho in 2001.

  1. How should this data set be cited?

  5. What is the general form of this data set?

    Geospatial data presentation form: remote-sensing image

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Raster data set. It contains the following raster data types:
      • Dimensions 5837 x 4471 x 1, type Pixel

    2. What coordinate system is used to represent geographic features?

      The grid coordinate system used is Universal Transverse Mercator

      Universal Transverse Mercator
      UTM zone number: 12
      Transverse Mercator projection parameters:
      Scale factor at central meridian: 0.999600
      Longitude of central meridian: -111.000000
      Latitude of projection origin: 0.000000
      False easting: 500000.000000
      False northing: 0.000000

      Planar coordinates are encoded using row and column.
      Abscissae (x-coordinates) are specified to the nearest 10.000000.
      Ordinates (y-coordinates) are specified to the nearest 10.000000.
      Planar coordinates are specified in meters.

      The horizontal datum used is North American Datum of 1983.
