Parameters

input=name
Name of the input space time dataset
file=name
Input file with map names, one per line

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
