<H3>PARAMETERS</H3>
CDSAR is controlled by the following global parameters:
<P>
<pre>Name     Prompt                                  Count     Type
CDDIR    CD Directory                            1-64      Char
FILE     Database File Name                      1-64      Char
CDIC     CD Input Channel list                   1-2       Int
DBOC     CD Output Channel list                  1-2       Int
TEX1     Database Descriptive Text 1             0-64      Char
SARTYPE  SAR Type: ERS/RADARSAT                  3-8       Char
FLIPSAR  Flip Scan SAR Image                     0-3       Char
REPORT   Report Mode: TERM/OFF/filename          1-64      Char

The following parameters receive output:

ORBIT    Orbit Segment                           1         Int
A0SEG    SAR Scaling Offset Segment              1         Int
ASCALSEG SAR Scaling Gain Segment                1         Int
DBGC     Database Ground Control Segment         1         Int
</pre>
<H4>CDDIR </H4>
Specifies the name of the CD directory. All files should be
contained inside the directory.
<P>
<PRE>
 EASI&gt;CDDIR=&quot;cddir&quot;
</PRE>
See example on how to enter the CDDIR for different operating
systems.
<P>
<H4>FILE</H4>
Specifies the name of the PCIDSK file to receive data. This file
will be created automatically and must not already exist.
<P>
<PRE>
 EASI&gt;FILE=&quot;filespec&quot;
</PRE>
<H4>CDIC</H4>
Specifies the list of channels to read from the CD. For each channel
specified, a channel will be created on the PCIDSK file (FILE).
<P>
<PRE>
 EASI&gt;CDIC=i,j,...,p
</PRE>
<UL>
<LI> Ranges of channels can be specified with negative values. For
example: {1,-4,10} is internally expanded to {1,2,3,4,10}. 
<LI> Up to 16 channels can be specified. 
<LI> Duplicate channels are NOT allowed. 
<LI> For complex data image, CDIC(1) corresponds to the real image and
CDIC(2) corresponds to the imaginary image. 
</UL>
<H4>DBOC</H4>
Optionally specifies the output channel. This parameter is only for
single look complex data. If DBOC is set to 1, the real and imagery
part of the single look complex data will be converted into an
intensity image. If DBOC is set to 1 and 2, the real and imagery
parts will be stored separately into output channels 1 and 2.
<P>
<PRE>
 EASI&gt;DBOC=1            | convert the single look complex data into
                        | an intensity image
 EASI&gt;DBOC=1,2          | store real and imagery part separately
                        | into 1 and 2
 EASI&gt;DBOC=             | defaults to 1
</PRE>
<H4>TEX1</H4>
Optionally specifies a line of text describing the file. Typically
this would contain information identifying the location of the data
and the CD reference number.
<P>
<PRE>
 EASI&gt;TEX1=&quot;string&quot;
</PRE>
<H4>SARTYPE</H4>
Specifies whether the image is an ERS image or RADARSAT image.
<P>
<PRE>
 EASI&gt;SARTYPE=&quot;ERS&quot;            | the image is an ERS image
 EASI&gt;SARTYPE=&quot;RADARSAT&quot;       | the image is a RADARSAT image
</PRE>
<H4>FLIPSAR</H4>
If the input image is RADARSAT Scan SAR, this parameter specifies
whether the Scan SAR should be flipped north up and east right.
Default is YES. If FLIPSAR is set to NO, the user will not be able
to generate ortho image correctly using PCI satellite modelling
software.
<P>
<PRE>
 EASI&gt;FLIPSAR=                  | Flip image north up and east right
 EASI&gt;FLIPSAR=&quot;YES&quot;             | Flip image north up and east right
 EASI&gt;FLIPSAR=&quot;NO&quot;              | Do not flip image
</PRE>
<H4>REPORT</H4>
Specifies where the CD information report should be directed. This
report contains CD header and orbital information.
<P>
<PRE>
 EASI&gt;REPORT=&quot;filename&quot;
 EASI&gt;REPORT=                   | defaults to terminal output
</PRE>
Note: The following names have special meaning:
<P>
<PRE>
 EASI&gt;REPORT=&quot;TERM&quot;     | generates reports on your terminal
 EASI&gt;REPORT=&quot;DISK&quot;     | generates reports on file &quot;IMPRPT.LST&quot;
 EASI&gt;REPORT=&quot;OFF&quot;      | cancels report generation
</PRE>
<H4>ORBIT</H4>
This parameter receives the number of the segment in which the
orbital information was saved.
<P>
<H4>A0SEG</H4>
This parameter receives the number of the array segment created to
receive the SAR scaling offset read from the &quot;Radiometric Data&quot;
record, if one was processed.
<P>
<H4>ASCALSEG</H4>
This parameter receives the number of the array segment created to
receive the SAR scaling gain table read from the &quot;Radiometric Data&quot;
record, if one was processed.
<P>
<H4>DBGC</H4>
This parameter receives the number of the segment of Ground Control
Points read from the SAR data records. If the GCP information is not
available from the SAR data records, no GCP segment will be
produced. If the GCP information is available, up to 255 geographic
(&quot;LONG/LAT&quot;) GCPs are produced.
