[GRASSLIST:7018] v.in.ogr

hi grass-friends,

i imported a shape-file by v.in.ogr with the option to create a new location. the shape-file has the following projection-file (produced by arcgis)

PROJCS["MGI_M31",GEOGCS["GCS_MGI",DATUM["D_MGI",
SPHEROID["Bessel_1841",6377397.155,299.1528128]],
PRIMEM["Greenwich",0.0],
UNIT["Degree",0.0174532925199433]],
PROJECTION["Transverse_Mercator"],
PARAMETER["False_Easting",0.0],
PARAMETER["False_Northing",-5000000.0],
PARAMETER["Central_Meridian",13.33333333333333],
PARAMETER["Scale_Factor",1.0],
PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]

then in the v.in.ogr-window the following text comes up:

v.in.ogr dsn=/home/helli/grassimport/obere_donau.shp output=n2k min_area=0.0001 snap=-1 >location=odast
A datum name hermannskogel (Militar_Geographische_Institut) was specified without transformation >parameters.

Now select Datum Transformation Parameters
Enter 'list' to see the list of available Parameter sets
Enter the corresponding number, or <RETURN> to cancel request

my questions are now:
-where can i get the information for the right datum transformation parameters?
-where have i to enter “list” for displaying the available parameters?
-where have i to enter the corresponding number?
-maybe in the v.in.ogr-window or in the grass-shell?

greetings from the tyrol with thanks in advance
helli

my questions are now:
-where can i get the information for the right datum transformation
parameters?

from the "list" .. the given info in the shp file is ambiguous, so you
get to choose.

-where have i to enter "list" for displaying the
available parameters?
-where have i to enter the corresponding number?
   -maybe in the v.in.ogr-window or in the grass-shell?

The module wants input. The Tcl GUI window can't take input.

You'll have to run the command from the command line, it is listed
at the top of the output above:

v.in.ogr dsn=/home/helli/grassimport/obere_donau.shp output=n2k \
    min_area=0.0001 snap=-1 location=odast

when it asks you to type "list", type it in the shell window.

long term the GUI structure or the module needs to be fixed to
address this.
