## DESCRIPTION

v.patch allows the user to combine any number of vector map layers together to create one composite vector map layer. If the table structures are identical, attributes are transferred to the new table.

## NOTES

Any vectors that are duplicated among the maps being patched together (e.g., border lines) will have to be edited or removed after v.patch is run. Such editing can be done automatically using v.clean (tool=snap,break,rmdupl).

## EXAMPLE

    v.patch input=geology,streams out=geol_streams

## SEE ALSO

v.clean, v.build, v.select, v.overlay
