Dylan,
If I remember, your patch is to d.measure? We don't use any of the old
interactive xterm commands. In fact, you can't use them anywhere
except in an xterm.

Given a raster, how do I produce a raster of the N times coarser
resolution (and with the same extent), such as:
* the values of the target raster's pixels are the mean values
of the corresponding source raster's ones;

As Hamish mentioned a couple messages up in this thread, it would be a
good idea (if it hasn't already been done) to formalize these type of

1) g.region set to smaller region;
2) r.mapcalc small=large

Hi list,
I should crop a small area out of a large raster layer (3GB) to make it
more manageable. I don't seem to find a quick way to do this.
Is there a function that just takes, xy or column row input to extract a
small subset and write it to a new (independent) layer?
Kind regards,
Koen

Thanks Maciej.
However, the 1st solution will take as long (maybe longer) than
importing the points from their original file again. I'll see if
v.transform will do it in one step.

If it's helpful, you can also extract attributes to individual .shp
files using ogr2ogr -where. For example
ogr2ogr -where 'cfcc = B11' output.shp input_file.rt1 CompleteChain
(B11 is the TigerLine attribute code for main line railroads)
The individual layers can then be brought into GRASS.
I found small issue with v.patch
If set of lines are patched to one file, v.bulid is necesarry to rebulid
topology. On the other way categories cannot be uploaded to database
(OUT OF MEMORY error mesage!). After v.build all works OK.

right, v.transform could do the job
v.transform -t in= out= zshift=
or
v.transform -t in= out= col='zshift:col_name'

Hi All,
I just went through the painful process of fixing a badly geo-referenced
vector against another vector. I used v.transform and a correspondence
file to do the work. The module works really well. However I wonder
whether it would be possible to modify the existing geo-referencing
plugin
