Patch (merge) the two vector maps together (I'm using roadsmajor and streams from the North Carolina sample dataset for GRASS GIS):
v.patch input=roadsmajor,streams output=roads_and_streams
Export using GDAL/OGR:
v.out.ogr input=roads_and_streams format=DXF output=roads_and_streams1.dxf
Alternatively, export using specialized module:
v.out.dxf i=roads_and_streams o=roads_and_streams2.dxf
Just for checking the resulting geometries, I imported both files back to GRASS GIS using always the other complimentary tool (v.in.dxf
for v.out.ogr
output and v.in.ogr
for v.out.dxf
output).
To do this in GUI, just use the (Command) Console tab, paste the name of the module (e.g. v.patch
), press Enter, and fill the dialog.
