Hi!
I have a high-res satellite image which has a positioning error about 5 m.
A previous GRASS version had a simple shift of coordinates however in the
GRASS-7 I cannot find such a tool.
A workaround is to use i.rectify. It seems to me that there could be a
more simple possibility for such a simple operation.
The image is large and i.rectify returns ERROR: Error writing segment
file. I get this error even after splitting the image and trying to
rectify a small piece of the large image. The procedures I did were:
- defined a small region
- with r.resample made a copy of the small region of the original large
map
- r.info reports the correct new region and the correct size of the small
map
- i.rectify of the new small map reported in the output window the
previous large region and I got the same error: Error writing segment
file.
I could to run i.rectify on another PC which has a bit more memory (4G, my
PC can use 3.2G, both are Linux), but anyway, to shift a raster should be
more simple.
Thanks for suggestions!
