[GRASS-user] v.transform - output messages

GRASS GRASS user

hi,

i want to move a large polygon-layer by "v.transform " with the following options:

v.transform
input=schiechtl_stern_m28
output=fwoe_mm28_tf45
xshift=-450000.0
yshift=0.0
zshift=0.0
xscale=1.0
yscale=1.0
zscale=1.0
zrot=0.0

so a -450000m-shift on the x-axis,

when i start, i get the following
output-messages:
...
...
...
V_ask error: Illegal row (40) in call to V_const
V_ask error: Illegal row (40) in call to V_ques
V_ask error: Illegal row (40) in call to V_ques

what do this messages mean? i can`t say, if the transform ist ok, because the transformation is still going on (...V_ask error: Illegal row (307) in call to V_ques...).

i tried this v.transform with grass6.1, grass6.2RC2, grass6.3-cvs-snapshot last weekend, always the same messages

with thanks in advance and greetings from austria

p.s. is there something similar like v.transform for raster data to move/shift raster data inside grass?

now i want to move all the polygones in one direction

I don't know but it's not normal I would say. If you could reproduce
that with sperfish60 and submit a bug report with how to reproduce
instruction it could incline some Grass developer to fix it. Could you?

p.s. is there something similar like v.transform for raster data to move/shift raster data inside grass?

r.region. But it's not that straight-forward as v.transform - you have
to manually calculate the region bounds (N,S,E,W) given the shift you
need, then apply this new region bounds to your raster.
