regres

Compiled by KD

Description

The program regres takes position and SPICE file information from SPC and puts it in files for export to other users. Specifically, that other user has mainly been KinetX so they can use SPC info in their navigation software.

For regres to run, a directory called "REGRES_FILES" needs to be made in the working directory. When regres is then run, export files for each picture are made (<PICTURE NAME>.TXT) and placed in the REGRES_FILES directory.

All pictures in PICTLIST.TXT will be used to make the exported regres files along with landmarks in LMRKLISTR.TXT. However, if a PICTLISTR.TXT has been made, regres will only use the pictures from that file when making the exported regres files.

Input Files

• PICTLIST.TXT or PICTLISTR.TXT

• LMRKLISTR.TXT

Output Files

• <path to working directory>/REGRES_FILES/<pixture name>.TXT
