Hi,
some vector maps from nc_spm_08 uses double precision column as key
column. Then some modules fails...
v.info geology -c --q | grep cat
DOUBLE PRECISION|cat
v.extract in=geology where="cat > 10 and cat < 20" out=geology1 --o
[...]
ERROR: Column <cat> is not integer
See [1]. A wild guess: grass7 uses gdal and not the internal shapelib to
open dbf files? At least in gdal-1.6.2, column <cat> would be
interpreted as double because field length is >10. The <cat> column of
geology is really integer, not double, because there are 0 decimal places.
