<H1>KEYWORDS -- List of Keywords</H1>
The ability to retrieve information has been greatly improved
through the use of keyword searches.  Every EASI/PACE program
has keywords associated with it, and users can search for
programs by using keywords, through the EASI and Xpace interfaces.
In order to assist the user in utilizing the keyword search
utility, this guide to common keywords has been compiled.<p>
A specific keyword has been assigned to each PACE package:
<P>
<PRE>
 airortho      (Airphoto Ortho and DEM)
 atmcor        (Atmospheric Correction)
 avhrr         (AVHRR Orbital Navigation)

Proper names are commonly used as keywords:

</PRE>
Keywords reflect what the program does:
<P>
<PRE>

 supervised    unsupervised    clustering
 print         map             average
 rewind
</PRE>
<UL>
<LI> All programs which produce a report have the keyword report.
<LI> All programs which transfer data (i.e. from disk to file) have
the keyword transfer.
</UL>
Keywords reflect the data or image type(s) utilized by the program:
<P>
<PRE>
 bitmap        image           signature
 vector        DEM             stereo
 airphoto      epipolar        projection

 spotimage     header          histogram
 LUT           PCT             eigenchannels
 drainage      network         watershed
 erdas         foreign         BSQ
 BIL           BIP             interleaved
 AES           TIROS           NOAA
 AVHRR         PAMAP           dipix
 georeferenced PCX             postscript
 eps           uncorrected     geocoded
 TIFF
</PRE>
Remember that keywords are case-insensitive.  Remember also that the
smaller the word you search on, the more &quot;hits&quot; you are likely to
receive.  For example, searching for &quot;ortho&quot; will find all
occurrences of orthorectification and orthorectify.  However,
searching for &quot;rectify&quot; will find orthorectify, but not orthorectification.
