r.mapcalc 'newmap=if(oldmap>=-0.01 & oldmap<=0.01, 0, oldmap)
You can also use r.recode.

Does anyone know of an open source utility to read magnetometer/gradiometer
dumped in GeoScan binary format as *.GRD and *.DAT files? In other words
something to use geophysical survey instrument data without needed proprietary
instrument vendor software?
Thanks

Or maybe you can use r.null:
r.null map=YourRASTER setnull=-0.1-0.1 null=0

r.mapcalc "new_raster=if(old_raster>-0.01 && old_raster<0.01,0,old_raster)"

I am trying to compile GRASS 7 svn (9Jul2011) snapshot on Ubuntu natty
(11.04) but without any success.
I followed the instructions from
http://grass.osgeo.org/wiki/Compile_and_Install#Platform_Specific_Notes
and I run configure as:
./configure --with-tcltk-includes="/usr/include/tcl8.5"

Hello Grass users,
I have a (hopefully) quick question - I would like to replace all values in a
raster that fall in the range -0.01 to 0.01 (i.e. 0.01><-0.01) with 0 but can't
quite work out how to express this in mapcalc.
Can anyone set me on the right track?
Thanks for reading,

Hi,
i have one raster and one vector file and i want to match them at the diplay
map. I want to change the coordinates of one of them, i guess specifying the
right coordinate reference system can do the job. How can i do this at Grass?
In Quantum is very easy, from the layer Properties, in Gra
