27 Parameters:
28 map=name
29 Name of input vector map
30

33
34 option=string[,string,...]
35 Build topology or dump topology or spatial index to stdout
36 Options: build,dump,sdump,cdump
37 Default: build
38 build: build topology
39 dump: write topology to stdout
40 sdump: write spatial index to stdout
41 cdump: write category index to stdout
42
44 v.build builds support files for (binary) GRASS vector data files.
45 These support files supply topology and category information that are
46 needed by other GRASS modules.
47
48 GRASS is generating these support files automatically, only in rare
49 cases the user has to (re)build them.
50
51 Refer to Vector data processing in GRASS GIS for more information on
52 GRASS GIS vector data model.
53
55 v.build creates support files only for binary vector maps located in
56 the user's current mapset. If vector map is located in another mapset,
57 you need to specify this:
58
59
60 v.build map=geology@PERMANENT
61
62
63 In case of errors, the user can optionally generate an error vector map
64 containing the erroneous vectors for later inspection.
