in photo.rectify, is it just the setting of the corresponding output map
names which is needed before the calculation begins, or is there more
to fill in past that first screen?
There are two sets of inputs - the output map names, and subsequently,
the output region definition, with a choice between using the existing
or one calculated using the rectification parameters (with the option to
edit it). I guess that this could be simplified to a parameter choosing
between using the existing region (which could be set prior to the
rectification) or the calculated 'minimal' region, using the existing code.
I think photo.rectify is the key as all the other elements of the
i.ortho.photo sequence generate text files in the group directory to
store the parameters, and these could be created independently
so that's the only one that takes much computational time right?
Yes.
I hope that helps - I'm currently using the GRASS 6.3 binaries in
Cygwin. Is it naive to assume that I can compile your updated
i.ortho.photo code and drop it into my 6.3 install?
Cheers,
Andy
