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.
