Hello,
has anyone out there i.rectified2 a plane bitmap (x,y) onto a DEM (globe)
using the latest i.rectify2 module? (CVS)
Here is what i did:
1. r.in.ppm of the image into imagery dataset
2. logged out / logged into world dataset
3. g.region of target area
4. log out of world dataset -> imagery
5. i.group & i.target & i.points
6. i.rectify2 (3rd order poly (but didn't matter on later tries))
7. got a mail: couldn't write row ...
I checked diskspace but there was plenty left (~several GB)
(imager cell size is 20mb)
resolution of world dataset ~0:0:30
resolution of imagery dataset ~1point/km
(I took the commands from gr-tut98.ps & and imagery.ps)
After digging into the mailinglist i found that several people had
already a try on this, so i decided to ask here.
regards,
Christoph
PS: Anyone having bathymetry/seafloor data (1-2 minute/1meter vertical) in
compressed (gzip/bzip2) form as i'm trying to produce a r.tides module

HI Christoph,
you need at least GRASS 5 beta7. Otherwise it won't work.
Which GRASS 5 do you have?
Cheers

r.in.tiff
seems to be broken if tifflib has -ljpeg and -lz compiled in.
I try to fix this using a smarter configuration test

Christoph
