NAME - Creates topology for GRASS vector map.


vector, topology

SYNOPSIS help map=name [error=name] [option=string[,string,...]] [--overwrite] [--verbose] [--quiet]


Allow output files to overwrite existing files
Verbose module output
Quiet module output


Name of input vector map
Name for vector map where erroneous vector features are written to
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 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 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: map=geology@PERMANENT

In case of errors, the user can optionally generate an error vector map containing the erroneous vectors for later inspection.
