LAS New User Tutorial

Function:

This program provides an interactive training session for the new LAS 5.2 user. Basic TAE commands and functions used in LAS 5.2 are demonstrated.

Description/Algorithm:

The New User Tutorial assists the user to become familiar with LAS 5.2. The tutorial includes sections on using help, LAS libraries, defining LAS commands, image information, and pixel data. Other sections cover tutor, command, and menu modes, and using batch queues.

After reading an explanation of each section, the user is given an opportunity to try the command for themselves. When running several of the commands in tutor mode, the parameters will disappear. The following list contains parameters for those functions.

The TESTGEN function is described in the TUTOR mode section.

  1. Invoke module TESTGEN-UNI by typing:  'TUTOR TESTGEN-UNI'
     At the TUTOR prompt, give parameter 
         OUT a value of x:                   'OUT=x' 
         PIXVAL a value of 10:               'PIXVAL=10,20,30'
         NBANDS a value of 3:                'NBANDS = 3'
     Save this set of parameter 
         values (including defaults):        'SAVE'  
     Return without executing the module:    'EXIT'  
  

 
  2. Invoke module TESTGEN-UNI:            'TUTOR TESTGEN-UNI' 
     At the TUTOR prompt, recall 
     the SAVEd set of parameter values:      'RESTORE'    
     Change the output name to a:            'OUT = a'    
     Let the module execute:                 'RUN'        
     type:                       'TUTOR-NOSCREEN  TESTGEN-UNI' 
     then:                       'LIST'

     This time, give OUT a value of z,       'OUT=z' 
     PIXVAL the values of 5, 6, and 7.       'PIXVAL=5,6,7' 
     and NBANDS the value of 3.              'NBANDS = 3'
     Now type:                               'RUN'  



The MATH function is described in the SUBCOMMAND section.

     To invoke MATH type:                  'TUTOR MATH' 
     At the subcommand menu, type:           '-ADD' 
     Assign parameter:	 
     		                             'IN = a z' 
				             'OUT = b' 
		     and                     'OFFSET = 50'
     Then type:                              'RUN' 
     to execute this subcommand of module MATH.
