NAME

       v.build  - Creates topology for GRASS vector map.

KEYWORDS

       vector, topology

SYNOPSIS

       v.build
       v.build help
       v.build map=name  [error=name]   [option=string[,string,...]]   [--overwrite]  [--verbose]
       [--quiet]

   Flags:
       --overwrite
           Allow output files to overwrite existing files

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       map=name
           Name of input vector map

       error=name
           Name for vector map where erroneous vector features are written to

       option=string[,string,...]
           Build topology or dump topology or spatial index to stdout
           Options: build,dump,sdump,cdump
           Default: build
           build: build topology
           dump: write topology to stdout
           sdump: write spatial index to stdout
           cdump: write category index to stdout

DESCRIPTION

       v.build builds support files for (binary) GRASS vector data files.   These  support  files
       supply topology and category information that are needed by other GRASS modules.

       GRASS  is generating these support files automatically, only in rare cases the user has to
       (re)build them.

       Refer to Vector data processing in GRASS GIS for more information on GRASS GIS vector data
       model.

NOTES

       v.build  creates  support  files only for binary vector maps located in the user's current
       mapset. If vector map is located in another mapset, you need to specify this:

       v.build map=geology@PERMANENT

       In case of errors, the user can optionally generate an error  vector  map  containing  the
       erroneous vectors for later inspection.
