In GRASS-6.x is there a way to modify the

attribute tables?
This is interesting. I opened the .dbf in OO.o and there are the
county
names in the attribute column, 'NAMES'. When I query the table with the
db.*
tools I don't see the names, only the numbers in the previous two
columns.
Also, when I try to export the table I see errors and nothing is
exported:
GRASS 6.5.svn (Nevada-aea):~/grassdata > db.out.ogr in=county_bnd
dsn=/home/rshepard/counties for=""
db.out.ogr is a wrapper around v.out.ogr, which forces "type=point".
SInce your county_bnd is probably a polygon layer, you probably want to
export to CSV the centroids (which hold the attrib data). Try this:
v.out.ogr county_bnd olayer=county_bnd dsn=/home/rshepard/counties
format=CSV type=centroid
WARNING: The map contains islands. To preserve them in the
output map, use
the -c flag
WARNING: 47 boundary(ies) found, but not requested to be exported.
Verify
'type' parameter.
WARNING: 17 centroid(s) found, but not requested to be exported. Verify
'type' parameter.
WARNING: 17 areas found, but not requested to be exported. Verify
'type'
parameter.
WARNING: No points found, but requested to be exported. Will skip this
geometry type.
WARNING: Nothing to export
If I'm asking for attribute data to be exported from the .dbf why do
I get
errors about geographic attributes?
Confused, but wanting to learn,
Rich
