GRASS GIS: v.build

NAME

v.build - Creates topology for GRASS vector data.

KEYWORDS

vector, topology

SYNOPSIS

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

Flags:

--overwrite: Force overwrite of output files

Parameters:

map=name: Name of input vector map
error=name: Name of vector map where erroneous vectors are written to
option=string[,string,...]: Build topology or dump topology or spatial index to stdout
build - build topology
dump - write topology to stdout
sdump - write spatial index to stdout
cdump - write category index to stdout; Options: build,dump,sdump,cdump; Default: build

DESCRIPTION

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

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 files located in the user's current mapset. If binary file 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.
