NAME

       v.info  - Outputs basic information about a vector map.

KEYWORDS

       vector, metadata, topology, extent, history, attribute columns, level1

SYNOPSIS

       v.info
       v.info --help
       v.info [-hcget] map=name  [layer=string]   [--help]  [--verbose]  [--quiet]  [--ui]

   Flags:
       -h
           Print history instead of info and exit

       -c
           Print types/names of table columns for specified layer instead of info and exit

       -g
           Print region info in shell script style

       -e
           Print extended metadata info in shell script style

       -t
           Print topology info in shell script style

       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       map=name [required]
           Name of vector map
           Or data source for direct OGR access

       layer=string
           Layer number or name
           Vector  features  can have category values in different layers. This number determines
           which layer to use. When used with direct OGR access this is the layer name.
           Default: 1

DESCRIPTION

       v.info reports some basic information (metadata) about a user-specified vector map and its
       topology status.

       If topology info is not available (i.e., vector map cannot be open on level 2), vector map
       extends and number of features need to be counted on the fly which may take some time.

EXAMPLE

   Basic metadata information

       Note: The Python tab in the wxGUI can be used for entering the following code:

       import grass.script as gcore
       gcore.vector_columns(’geology’)   # for `v.info -c`
       gcore.vector_info_topo(’geology’) # for `v.info shell=topo`
