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.
