[GRASSLIST:3731] problem import shape file

[Marco Kienzle]

Hi,

I am having many problems trying to import a .shp file (from ESRI) using
v.in.shape command although if the input file is a simple grid. The
problem is that in the resulting file many polygons have a area equal to
zero ??

I import the file with the following commands:

v.in.shape -o input=/home/kienzle/GIS/GRASS/poubelle/icesshape.shp
attribute=JOIN label=ICESSQ

Receive many of the following warnings:

WARNING: area 375 label: 1059 matched another label: 1059.
WARNING: area 406 label: 1060 matched another label: 1060.
WARNING: area 437 label: 1061 matched another label: 1061.
WARNING: area 468 label: 1062 matched another label: 1062.
WARNING: area 499 label: 1063 matched another label: 1063.
WARNING: area 530 label: 1064 matched another label: 1064.


And then check for the result with
v.report map=icesshape type=area units=k


Am I doing something wrong ? Is there something wrong in the original
file (although it works under ARC-INFO)?

thanks in advance,
marco
