Abstract:
This is a spectrally enhanced 50-meter pixel-resolution
Landsat-MSS mosaic of Utukok_River. This 3-band composite
contains three Landsat-MSS spectral channels: image band-1 contains
Landsat MSS channel-1, image band-2 contains Landsat MSS channel-2,
and image band-3 contains Landsat MSS channel-4.

This 50m-pixel-resolution image is a direct subset of a 50m-pixel-
resolution, 3-band parent-image product, also available on this data
server. This Quadrangle-based subset was created to reduce the image
file size. Adjacent Quadrangle subsets can be concatenated (allow data
values to overwrite zero values) to build larger seamless images.
The remainder of this metadata describe the full 50m-resolution,
3-band parent image that covers the entire north slope of Alaska,
except that the bounding extents are changed to reflect the respective
USGS Quadrangle (1:250000-scale) boundaries.

Numerous Landsat-MSS scenes were mosaiked together by the USGS EROS Data
Center, Sioux Falls, SD. Originally, the Landsat scenes were mosaiked
into two separate image composites (western north slope and eastern
north slope), each in a slightly different Albers Equal Area projection.
The Landsat image ID-numbers, acquisition dates, path-row, and
projection parameters used in the original 2 east/west composites were:

into a single image by the USGS/BRD Alaska Biological Science Center:

The image file is distributed with several other documenting files
for compatibility with ARC/INFO Image Integration commands:
*.bsq - actual binary image file, band-sequential
*.bsqw - pixel dimensions and upper-left x,y pixel coordinate
*.stx - band statistics (can be modified to change contrast stretch)
*.prj - projection parameters
*.hdr - image file dimensions and format

Purpose:
This enhanced color composite was created to provide a broad-scale georeferenced image that can be used for visual interpretation, especially as a back-drop for overlaying other geospatial 'vector' databases that can be found on this server (eg. animal distributions, rivers, political boundaries, etc.). This product was intended to be useful in regional resource assessments conducted on the north slope of Alaska.
Supplemental_Information:
The parent file is very large - 622,566,186 bytes. Many potential users may not be interested in the entire area, or they may not have computer resources with sufficient capabilities to work with such a large image file. Available on this data server are smaller image files that are direct subsets of the entire, full-resolution (50m pixel) image. One subset has a coarser pixel-resolution (100m pixel) and only 2 bands (Landsat MSS bands 2 and 4, binary image file size = 100,632,130 bytes). The remaining subsets are spatial extractions of the full-resolution, 3-banded image, based on USGS 1:250000 Quadrangle boundaries. Adjacent Quadrangles can be concatenated (allow zero-value pixels to be overwritten by pixel values greater than zero) to produce seamless images. Metadata for the Quadrangle-based subsets are identical to the metadata of the parent file, except that the dataset title and bounding coordinates have been changed.
