[GRASSLIST:1462] Maiking GRID

GRASS GRASS user
1

Hi Grass Users,
                I have got a raster image. The image has latitudes and longitudes marked as vertical and horizontal lines with a difference of 4 degrees. I want to palce a grid of 1 degree x 1 degree in ecah 4 degree x 4 degree grid. So that the resultant map has latitudes and longitudes with a grid resolution of 1 degree x 1 degree. It is possible in "Mapinfo" software. How that can be done in GRASS. Please help.

Thanks,

uttam.

d.grid? If it is a projected location maybe you have to do some
size=(cos)latitude/(60*1852) origin=+x,+y math by hand. (->wish?)
