If you use the -cuo option in azatm to change the values it's supposed to set overflowed and underflowed pixels to, it doesn't seem to have an effect - always sets underflowed pixels to 0 (even if told to set them to ffff) and always says:

************* radcal underflow and overflow fill values changed ********
      under : 00000  = 0     over: 00000  = 0

...in azatm output, regardless of what values are entered for the under/overflow (tried with 0 fffe and ffff ffff).

People at RSPSoc strongly expressed a wish to have orthorectified photos. This is a huge chunk of work and very manual to do the full process using the Leica workflow. Other workflows may improve this, e.g.

• azgcorr
• Susan Conway suggested ​http://en.wikipedia.org/wiki/SOCET_SET and

similar helped a lot

• John Stevenson managed some of this with GRASS

ARSF-DAN agreed to investigate this as a background, low priority task. In particular, it may be worth considering a halfway house (tiepointing & colocating, which can be automatically done, but not seamlining, which is intensively manual at present).

Build number: 2010.01.18.1 system : pmpc974

to reproduce, run lag with no arguments, click file, open, select any file and click add or refresh. the file will be loaded but won't appear on screen until either the pan or zoom options are used. the flight line should appear immediately after loading is concluded.
