[GRASS-user] v.to.3d -r option not working properly

[Pedro Venâncio]

Hi Anna,


 Then I wanted to transform the z-coordinate to
>

>> v.to.3d -r input=contour_3d col="CONC" output=contour_2d
>> (I added CONC column to contour_3d before, using v.db.addcol

>> columns="CONC double precision").

It is not possible to avoid this procedure, of creating the new column in
the layer of origin (3d layer), to get the height column in the 2d layer?
Something like the 'column' parameter of v.random (Name of column for z
values; Writes z values to column), where we just give a name to the height
column in the resulting layer?

Will this be backported to 7.0.x?


Thank you very much!

Best regards!
