SYNOPSIS

13       v.patch
14       v.patch help
15       v.patch [-ae] input=name[,name,...] output=name  [--overwrite]

18       -a  Append files to existing file
19
20       -e  Copy also attribute table. Only the table of layer 1  is  currently
21           supported
22
23       --overwrite
24
25   Parameters:
26       input=name[,name,...]
27           Vector map(s) -- source for composite
28
29       output=name
30           New vector composite

DESCRIPTION

33       v.patch  allows  the  user  to  combine any number of vector map layers
34       together to create one composite vector map layer.  If the table struc‐
35       tures are identical, attributes are transferred to the new table.
36

NOTES

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