[GRASS-user] Help on worldfile info or g.region

Hello,

I'm a bit confused at the moment, but I thought that
-the grass region defines the outer edge of a region
-as well as the worldfile for a graphic does

Am I wrong? I've imported a graphic with the following worldfile:
2
0
-2
4280000
5610000

but g.region on that file gives:
north: 5610001
south: 5606001
west: 4279999
east: 4283999
nsres: 2
ewres: 2
rows: 2000
cols: 2000
cells: 4000000

so what did I do wrong? Is g.region defining the cell center or does this the worldfile.

Thanks for any help

To correct myself it seems that the Worldfile specifies the center of the upper/left cell and not the bounding box.

Regards
Wolfgang
