in the GUI startup you could try "create new location from EPSG code",

Dear all,
I have a raster map with categorical values.
I have many occurrence of alone-pixels, where all neighbours
are different from a central pixels. So I need to change all pixels
that differ from alll its neighbours for the "mode" value.
I know that "r.neighbours ..method=mode" return the mod
Hi,
I want to create a LOCATION corresponding to JGD2000 CS III which
is defined in epsg.
I tried to create it as following,
coordinate system : Other Projection
projection name : tmerc

ellipsoid name : GRS80
towgs84=0,0,0,0,0,0,0
Scale Factor : 0.

Hi,
Just installed GRASS 6.3.0... When I try to launch it with its Python
GUI I see this error :

My only remaining question is: Is there a way to use the track raster
file to input the values instead of using the mouse, so that the
process can be more or less automated? Thank you all for your great
help. I'll write a summary and post it in the Wiki as an FAQ
