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 [EMAIL PROTECTED] 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.
