check_net Documentation

check_net - check that all images are connected by match points
check_net takes in a matchpoint file, and determines which sets of
matchpoints are connected. All should be connected in a solution,
if they're not, the output helps to find where the problem is.

ADDITIONAL NOTES:

Parm	Description
FROM	This is the file containing tie points. They can either be pixel match points in the qmatch format, or millimeter points in the RAND millimeter measurement format. FILETYPE needs to be set accordingly.
TO	The output file prefix. If this is "out.dat", for example, the first set of connected images will be in "out.dat.1". If the network isn't connected and there exist other sets of connected images, they will be in "out.dat.2", "out.dat.3", and so on.
FILETYPE	Input file type. Either qmatch (for qmatch pixel measurements) or mm (for RAND millimeter measurements)
DATFMT	The data format for millimeter measurement files. The formats are the same as those for randlsq (view the randlsq documentation for more info). The main difference is that RAND formatted files have a maximum point ID length of 5 characters, while RANDCLEM formatted files have a maximum point ID length of 7 characters.
