MCTP

Places a file containing control points for the specified frame into an image based information system (IBIS) tabular file

Function:

Places a file containing control points for the specified frame into an image based information system (IBIS) tabular file. This file can be an ASCII file, a labeled table file, or a tiepoint location file.

Parameters:

Subcommand -ASCII:
Creates an IBIS tabular file from an ASCII file.

NOTE: This file must have three header records at the beginning of the file. They are column dependent as shown in the following list.


Columns --    12345678901234567890
1st record --  TAB
2nd record --       nrows   ncolumns
3rd record --    columns the data should be placed into

FRAMNUM
Frame number. Frame number of the image whose associated ASCII file is being loaded into an IBIS tabular file.

DELFLG(YES)
Delete flag. Specifies whether or not the temporary file should be deleted upon procedure completion.


  = YES:  Delete temporary file.
  = NO:   Do not delete temporary file.
Subcommand -LT:
Creates an IBIS tabular file from a labeled table file.

FRAMNUM
Frame number. Frame number of the image whose associated labeled table file is being loaded into an IBIS tabular file.

DELFLG(YES)
Delete flag. Specifies whether or not the temporary file should be deleted upon procedure completion.


  = YES:  Delete temporary file.
  = NO:   Do not delete temporary file.
Subcommand -TPL:
Creates an IBIS tabular file from a tiepoint selection file.

FRAMNUM
Frame number. Frame number of the image whose associated tiepoint selection file is being loaded into an IBIS tabular file.

DELFLG(YES)
Delete flag. Specifies whether or not the temporary file should be deleted upon procedure completion.


  = YES:  Delete temporary file.
  = NO:   Do not delete temporary file.

Example:

  1. LAS> mctp-ascii framnum=1

    Assuming that the LAMS global $IMAGE(1) = "US1", the IBIS file US1.GCP is created from the ASCII file US1;CTP. The temporary file is deleted.

  2. LAS> mctp-lt framnum=1

    Assuming that the LAMS global $IMAGE(1) = "US1", the IBIS file US1.GCP is created from the labeled table file US1.CTP. The temporary file is deleted.

  3. LAS> mctp-tpl framnum=1 delflg = no

    Assuming that the LAMS global $IMAGE(1) = "US1", the IBIS file US1.GCP is created from the tiepoint location file US1.CTP. The temporary file is not deleted.

Description/Algorithm:

The procedure begins by setting up local file names for the current input frame. The IBIS tabular file containing the control points for this frame is created from the input file. Empty rows are deleted from the file. The "from frame" number and the "to frame" number are set. Finally, if specified, the temporary file is deleted. Error Messages: Error messages are displayed from the called routines.
