[GRASS-user] v.transform

[Dr. Manuel Seeger]

Hello all,
I transforming a huge 3D point vector file with v.transform and GCPs. I 
want to shift the elevation data but unfortunately the data is set to 
the constant value of shift or to 0 if I do not indicate shifting
 I`on an ubuntu 7.10, with grass 6.3 cvs from last week

Can somebody help?

In and output:

v.transform -m input=BAR1_geschnitten at PERMANENT output=BAR1_trans 
pointsfile=/home/seeger/Documents/GRASSDATA/Bardenas/BAR1_711_PP_transpose.txt 
xshift=0.0 yshift=0.0 zshift=342.12 xscale=1.0 yscale=1.0 zscale=1.0 
zrot=0.0 layer=1 --overwrite

New vector map <BAR1_trans> boundary coordinates:

 N: 4681879.885    S: 4681828.345

 E: 624832.091    W: 624761.947

 B: 342.120    T: 342.120

v.transform complete.
