I'm not sure v.out.ogr in its current state can export several layers at once. Try running v.out.ogr three times, changing layer each time and using the -u flag for updating the existing gpkg file: v.out.ogr -c input=pal output_layer=pal1 output=pal.gpkg layer=1 v.out.ogr -c input=pal output_layer=pal2 output=pal.gpkg layer=2 -u --o v.out.ogr -c input=pal output_layer=pal3 output=pal.gpkg layer=3 -u --o Moritz > > -k. > > > grass ./nc_spm_08_grass7/PERMANENT > > g.mapset -c gpgk > g.copy vector=poi_names_wake@PERMANENT,points > g.copy vector=lakes@PERMANENT,areas > g.copy vector=railroads@PERMANENT,lines > > v.category in=areas out=areas_2 op=chlayer layer=1,2 > v.category in=lines out=lines_3 op=chlayer layer=1,3 > v.patch in=points,areas_2,lines_3 output=pal > > v.db.addtable map=pal table="tbl_points" layer=1 > v.db.addtable map=pal table="tbl_areas" layer=2 > v.db.addtable map=pal table="tbl_lines" layer=3 > > v.db.connect -p map=pal > # Vector map <pal> is connected by: > # layer <1/tbl_points> table <tbl_points> in database > </home/kdm/data/grass/nc_spm_08_grass7/gpgk/sqlite/sqlite.db> through > driver <sqlite> with key <cat> # layer <2/tbl_areas> table > <tbl_areas> in database > </home/kdm/data/grass/nc_spm_08_grass7/gpgk/sqlite/sqlite.db> through > driver <sqlite> with key <cat> # layer <3/tbl_lines> table > <tbl_lines> in database > </home/kdm/data/grass/nc_spm_08_grass7/gpgk/sqlite/sqlite.db> through > driver <sqlite> with key <cat> # GRASS 7.4.0 > (nc_spm_08_grass7):~/data/grass > > > v.db.addcolumn map=pal layer=1 column="pt INT" > v.db.addcolumn map=pal layer=2 column="ar INT" > v.db.addcolumn map=pal layer=3 column="ln INT" > > v.db.update map=pal layer=1 column=pt value=42 > v.db.update map=pal layer=2 column=ar value=43 > v.db.update map=pal layer=3 column=ln value=44 > > v.out.ogr -c input=pal output=pal.gpkg --o > # WARNING: The combination of types is not supported by all formats. > _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
