DSPRGRD

Displays grid and transformation information in a grid file

Function:

Displays a radiometric mapping grid file. It provides the options of printing the file on the line printer, on the user's terminal, or to a text file. Polynomial coefficients, statistical measures of the model fit, and gridding error estimates are also reported.

Parameters:

INGRID
Input grid file. The input radiometric mapping grid file to be printed.

PRINT(TERM)
Output destination. The output destination of the radiometric mapping grid and related information display. The available output destinations are:


  = TERM:      Terminal.  Output is sent to the 
               user's terminal.  
  = LP:        Line printer. Output is ent to the 
               printer defined by $PRINTER.  
  = Filename:  User-supplied filename.  Output is 
               sent to the user-supplied file with
               the extension ".prt".

Examples:

  1. LAS> dsprgrd ingrid=testgrid print=term

    The contents of the radiometric mapping grid TESTGRID are displayed on the terminal.

  2. LAS> dsprgrd ingrid=grid.out print=(term,lp)

    The contents of the radiometric mapping grid file GRID.OUT are displayed on the terminal and printed on a printer.

Description/Algorithm:

The input and output image line and sample coordinates contained in the radiometric mapping grid file along with the transformation coefficients, statistical measures of the model fit, and gridding error estimates are displayed on the terminal and, optionally, are printed on a printer or written to a text file.

Nonfatal Error Messages:

    None.

Fatal Error Message:

  1. [dsprgrd-fatal] Fatal error encountered

    The error message that is displayed immediately preceding this message is the specific error that was encountered. Processing is terminated.

User Notes

  1. Mapping grid files may be produced by the function FINITE.

  2. This version of DSPRGRD does not support the plotting of radiometric mapping grids. It is planned that this capability will be added later.
