## NAME

t.unregister - Unregisters raster, vector and raster3d maps from the temporal database or a specific space time dataset.

## KEYWORDS

temporal, map management, unregister, time

## SYNOPSIS

t.unregister
t.unregister --help
t.unregister [input=name] [file=name] [type=name] [maps=name[,name,...]] [--help] [--verbose] [--quiet] [--ui]

### Flags:

--help
  Print usage summary
--verbose
  Verbose module output
--quiet
  Quiet module output
--ui
  Force launching GUI dialog

### Parameters:

input=name
  Name of the input space time dataset
file=name
  Input file with map names, one per line
type=name
  Type of the input map
  Options: raster, vector, raster_3d
  Default: raster
maps=name[,name,...]
  Name(s) of existing raster, vector or raster3d map(s) to unregister

## DESCRIPTION

This module is designed to unregister raster, 3D raster and vector map layers from space time datasets and the temporal database.

Map layer that should be unregistered from the temporal database can be specified as a list of comma separated map names or using a text file, that contains one map layer name per line. By default the map type that should be unregistered is set to raster. The optiontype must be used to specify 3D raster or vector map layer types.

## INPUT FILE FORMAT

Specification of map names:

    a1
    a2
    a3
    a4
    a5
    a6

### NOTE

In case the input option is used to specify a space time dataset the maps are only unregistered from the space time dataset, but not from the temporal database. The reason is that maps can be registered in multiple space time datasets and there is a need to unregister them from a specific STDS without affecting other STDS.

## EXAMPLE

In this example a precipitation map it is registered into temperature dataset, so the wrong map will be unregister.

    t.register -i type=raster input=tempmean_monthly@climate_2009_2012 \
        maps=2012_01_precip \
        start="2013-01-01" increment="1 month"

    # We unregister raster map 2012_01_precip from a space time dataset,
    # the raster maps are still present in the temporal database
    t.unregister type=raster input=tempmean_monthly@climate_2009_2012 maps=2012_01_precip

    # We unregister raster map 2012_01_precip from the temporal database, hence
    # the time stamps are removed
    t.unregister type=raster maps=2012_01_precip
