17
18   Flags:
19       -a
20           Append  files  to existing file (overwriting existing files must be
21           activated)
22
23       -e
24           Copy also attribute table
25           Only the table of layer 1 is currently supported
26
27       --overwrite
28           Allow output files to overwrite existing files
29
30       --verbose
31           Verbose module output
32
33       --quiet
34           Quiet module output
35
36   Parameters:
37       input=name[,name,...]
38           Name of input vector map(s)
39
40       output=name
41           Name for output vector map
42
43       bbox=name
44           Name for output vector map where bounding  boxes  of  input  vector
45           maps are written to
46

DESCRIPTION

48       v.patch  allows  the  user  to  combine any number of vector map layers
49       together to create one composite vector map layer.  If the table struc‐
50       tures are identical, attributes are transferred to the new table.
51

NOTES

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