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.
