Hi developers,
from my experience with i.ortho.photo I suggest
following small change in menu structure:
We have:
------------------------------------------------
i.ortho.photo -- Imagery Group = all
Initialization Options:
1. Select/Modify imagery group
2. Select/Modify imagery group target
3. Select/Modify target elevation model
4. Select/Modify imagery group camera
Transformation Parameter Computations:
5. Compute image-to-photo transformation
6. Compute ortho-rectification parameters
7. Initialize exposure station parameters
Ortho-rectification Option:
8. Ortho-rectify imagery files
RETURN exit
------------------------------------------------
I prefer:
------------------------------------------------
i.ortho.photo -- Imagery Group = all
Initialization Options:
1. Select/Modify imagery group
2. Select/Modify imagery group target
3. Select/Modify target elevation model
4. Select/Modify imagery group camera
Transformation Parameter Computations:
5. Compute image-to-photo transformation
6. Initialize exposure station parameters
7. Compute ortho-rectification parameters
Ortho-rectification Option:
8. Ortho-rectify imagery files
RETURN exit
------------------------------------------------
-> note that order of (6) and (7) are reversed.
Advantages:
- you will not get a warning that "exposure station parameters"
are not set, if you first set "exposure station parameters"
- you do not get a "Matrix inversion error" from
i.ortho.photo/libes/orthoref.c:
error ("Matrix Inversion (Control Points status modified)");
(my today's trap)
Disadvantages:
- I have to adjust the man page :-)
- nothing else known
Please send your comments, otherwise I may update
i.ortho.photo/menu/menu.c
the next days in CVS. This change is not very severe,
but I want to ask for agreement.
Best wishes
Markus Neteler
