Chestertown, Maryland Metadata file:

All satellite image files, TIF and Lan, were generated from the same
Landsat 7 ETM+ scene. Included in the download folder are three Lan
files that were generated using MultiSpec software. Due to different
download speeds and educational applications a smaller Lan file, 597 by
443 pixels, was subsetted from the larger 1000 pixel by 1000 pixel file.
Another larger Lan file was created to be used to study most of the
Chester River watershed, 1560 pixel by 1730 pixel file.

In addition to the Lan files, numerous color composite images were
generated using MultiSpec. Each of these images enhances different
features of the satellite image. The color composites were saved as Tif
files and retain their geographic information. The Tif color composites
were 2 percent tail clipped enhanced instead of showing the entire range
of the data. If the entire range is needed then a new image needs to be
generated using the MultiSpec display specification.

In the file name is the following information: yyyy = four digit year of
acquisition, mm = two digit month, dd = two digit day, PLACE = five
letters of location, s = a subset of the image. If new files are
generated from the Lan files using MultiSpecs' change image file format,
then it is recommended that above data remain in the file name. Also
this metadata file should be saved in the file folder to be referred to
in the future.

The Tif files use the same naming system for acquisition date and place
name. In addition, the channels used to create the 3 channel color
composite are included in the file name. The "chs" is the abbreviation
for channels used by MultiSpec. After the "chs" are the Landsat 7 ETM +
channel used. Below, see item number 3, which band of data corresponds
to which number is explained. Additionally, you can refer to the Landsat
PowerPoint
presentation**http://landsat.gsfc.nasa.gov/education/l7downloads/howto.html**,
to explain more about the uses of different color composite images.

\(3\) Thermal band was included as channel 7 in the lan file.

Which Landsat band is in which channel:

Landsat 7 ETM+ channel 1= band 1(Blue, 0.45 - 0.52 m)

Landsat 7 ETM+ channel 2= band 2(Green, 0.52 - 0.60 m)

Landsat 7 ETM+ channel 3= band 3(Red, 0.63 - 0.69 m)

Landsat 7 ETM+ channel 4= band 4(Near Infrared, 0.76 - 0.90 m)

Landsat 7 ETM+ channel 5= band 5(Mid Infrared, 1.55 - 1.75 m)

Landsat 7 ETM+ channel 7= band 6(Mid Infrared, 2.08 - 2.35 m)

Landsat 7 ETM+ channel 6= band 7(Thermal Band, 10.4 - 12.5 m)

BACKGROUND: The launch of the Landsat-7 satellite on April 15, 1999,
marks the addition of the latest satellite to the National Aeronautics
and Space Administration\'s Landsat satellite series. The Landsat-7
satellite carries the enhanced thematic mapper plus (ETM+) sensor and is
part of an ongoing mission to provide quality remote sensing data in
support of research and applications activities. Information on the
Landsat-7 Program, including information about the Landsat-7 satellite,
the ETM+ sensor, and Landsat-7 data collection, is available in the
\"Landsat 7 Science Data Users Handbook.\"
