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.
