[GRASS-user] Question about Datum not recognised by GRASS

[Zac45]

Hi,

I am quite new to GRASS and this is my first post, looking for some help
here!

I am now processing the dataset under *CGCS2000 / 3-degree Gauss-Kruger CM
120E*. But the dataset could not be recognised by GRASS when I trying to
import the DEM data.  The warning message kept poping up: 

WARNING: Datum <China_2000> not recognised by GRASS and no parameters found

And the output from g.region -p is:

projection: 99 (CGCS2000 / 3-degree Gauss-Kruger CM 120E)
zone:       0
datum:      ** unknown (default: WGS84) **
ellipsoid:  grs80
north:      1
south:      0
west:       0
east:       1
nsres:      1
ewres:      1
rows:       1​
cols:       1
cells:      1

How can I fix it?

Best,
Zac45
