4. region = the intersection of raster1 and raster2 --> ?
As far as i see, using the g.region command, there is no way to specify
the last point except to manually set the nord,sud,ovest and east
values, but unfortunately i can not use this way.
Is there any other command in GRASS that i can use instead of g.region
to set the current region as the intersection of two rasters?
Hello,
I assume you have some kind of programing language which executes grass
commands. Can you parse the output? If so then you could do it like this:
g.region rast=raster1
g.region -p (parse the output, into rast1north, rast1east, rast1west,
rast1south, etc)
g.region rast=raster2
g.region -p (parse the output, into rast2north, rast2east, rast2west,
rast2south, etc)
g.region north=(min of rast1north, rast2northe) etc for other parameters.
Hope this helps,

Hello Wolf
Yes, the service i'm developing is written in Java.
Your solution is a good one but the problem is the overhead it introduces.
Since i can't (or maybe i'm not able to :( ) interact directly with
GRASS using Java, i would need to make 4 files reading/writing.
thanx
