32 Default: build

35 v.build builds GRASS support files for (binary) GRASS vector data
36 files. These support files supply topology and category information
37 that are needed by other GRASS programs.
38
39 GRASS is generating these support files automatically, only in rare
40 cases the user has to (re)build them.
41
42 Refer to Vector data processing in GRASS GIS for more information on
43 Grass GIS vector data model.
44
46 v.build creates support files only for binary vector files located in
47 the user's current mapset. If binary file is located in another mapset,
48 you need to specify this:
49
50
51 v.build map=geology@PERMANENT
52
53
54 In case of errors, the user can optionally generate an error vector map
55 containing the erroneous vectors for later inspection.
