<p>COMMENTS:
<br>The purpose of this program is to provide satellite imagery of the
state of Ohio to researchers, teachers, the general public, and other potential
satellite data users. It is meant to serve experts and non-experts alike.
Urban growth, natural resource loss, and crop health are a few of the environmental
issues that may be monitored with this type of satellite data.
<br>The Landsat 7 satellite was launched in April of 1999.
This satellite orbits the earth and captures digital snapshots from space.
OhioLINK has purchased all Ohio based data captured by Landsat 7 since
the first data sets were available, and maintains a standing order for
new data as it is captured.
<p>A new 'snapshot' of the state is captured every 16 days.
A complete 'snapshot' of Ohio is represented by nine Landsat 7 scenes that
each represent ground cover approximately 115 miles wide by 106 miles long.
Within each scene, nine different 'layers' are captured. (These 'layers'
are actually different bands of the electromagnetic spectrum). These are
available via FTP for expert users. Additionally these are processed
at OhioLINK to create a variety of meaningful products viewable on the
web for other academic users and the public.
<br>OhioLINK acquires data with less than 30% cloud cover.</blockquote>
