Parameters

Name	Type	Caption	Length	Value range
MFILE *	String	Input files	1 - 192
BASENAME *	String	Basename of the flight line	1 - 192

Parameter descriptions

MFILE

The names of image files, a folder, or a text file that contains the input images to process. If necessary, you can use wildcards, such as the asterisk (*) in the value string.

If you use a wildcard, FLIGHTLINE processes all files that match the specified file-name pattern.

If you specify a folder, FLIGHTLINE processes all the recognized image files in that folder.

If you specify the the name of a text file, FLIGHTLINE processes the images listed in the file. Each image should be listed on a separate line. Any other entries that follow the file path and name on each line are ignored.

BASENAME

The basename of the flight line to print. This will be used to write the metadata tag.

BREAKANG

The break angle of a flight line, which is used to determine the end of a flight line. The vector angles between image centers are calculated, and if the vector angle between two image centers is greater than the break-angle threshold of the flight-line ends, a new one begins.

The default value is 22.5 (22.5 degrees).

This parameter is optional.

REPORT

Specifies where to direct the generated report.

Available options are:

• TERM: generates a report on the terminal (default)
• DISK: generates a report on file "IMPRPT.LST"
• OFF: turns off report generation
• <filename>: appends a report to the specified file

Details

Example

Process all of the photos in a particular folder to group them into their respective flight lines.

MFILE="halifax_16"
BASENAME="Halifax"
BREAKANG=                      ! use the default of 22.5 degrees
