I am getting an error code when I try to import a contour line vector file GRASS via QGIS. I have been trying to create a DEM from the contour lines following this tutorial:

When I try to import the loaded vector ( I get the following error message: "dsn=C:\GIS\Elevation\Florida Counties\Bradford\Bradford.shp" output=BradfordGrass2 snap=-1 min_area=0.0001 -o

Datum not recognised by GRASS and no parameters found

Over-riding projection check

Layer: Bradford

DBMI-DBF driver error:

Unable to create table: 'create table BradfordGrass2 (cat integer, FNODE_ double precision, TNODE_ double precision, LPOLY_ double precision, RPOLY_ double precision, LENGTH double precision, TOPO5_ double precision, TOPO5_ID double precision, CONTZ integer, CARRYZ integer, ELEV integer, WMD varchar ( 6 ), ADD integer)' Finished with error

I am using five-foot contour lines downloaded from downloaded the data from the FGDL.

Any suggestions as to how to fix this would be greatly appreciated.

Maybe the column name "ADD" is making trouble? – Micha Sep 15 '13 at 5:36
