<h2>DESCRIPTION</h2>

<em>i.spectral</em> displays spectral response at user specified 
locations in images.

<h2>NOTES</h2>

This script needs gnuplot to be installed.

<h2>EXAMPLE</h2>

North Carolina sample dataset:

<div class="code"><pre>
g.region rast=lsat7_2002_10 -p
LIST=`g.mlist type=rast pat="lsat7_2002_[1-5,7]0" fs=","`
i.spectral raster=$LIST east_north=637502.25,221744.25
</pre></div>

This will search all LANDSAT map for 2002 but select only the B, G, R, 
NIR, and MIR channels.
