t.vect.import(1grass) GRASS GIS User's Manual t.vect.import(1grass)
NAME
t.vect.import - Imports a space time vector dataset from a GRASS GIS
specific archive file.
KEYWORDS
temporal, import, vector, time, create location
SYNOPSIS
t.vect.import
t.vect.import --help
t.vect.import [-eoc] input=name output=name [basename=string] direc-
tory=name [title=string] [description=string] [location=string]
[--overwrite] [--help] [--verbose] [--quiet] [--ui]
Flags:
-e
Extend location extents based on new dataset
-o
Override projection check (use current location’s projection)
Assume that the dataset has same projection as the current location
-c
Create the location specified by the "location" parameter and exit.
Do not import the space time vector datasets.
--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog
Parameters:
input=name [required]
Name of input file
output=name [required]
Name of the output space time vector dataset
basename=string
Basename of the new generated output maps
A numerical suffix separated by an underscore will be attached to
create a unique identifier
directory=name [required]
Path to the extraction directory
title=string
Title of the new space time dataset
description=string
Description of the new space time dataset
location=string
Create a new location and import the data into it. Do not run this
module in parallel or interrupt it when a new location should be
created
DESCRIPTION
t.vect.import imports a space time vector dataset archive that was ex-
ported with t.vect.export.
NOTES
Optionally a base map name can be provided to avoid that existing vec-
tor maps are overwritten by the map names that are used in the STRDS
archive.
The directory is used as work directory in case of import but can also
be used as a data directory when using GML for the data exchange.
EXAMPLE
In this example, five vector maps are created and registered in a sin-
gle space time vector dataset named random_locations. Each vector map
represents random locations within the boundary of the state taken at 1
month intervals. The space time dataset is then exported and re-im-
ported.
db.connect -d
for i in `seq 1 5` ; do
v.random output=map_$i n=500 restrict=boundary_state@PERMANENT
echo map_$i >> map_list.txt
done

description="Vector test dataset with random locations"
t.register -i type=vector input=random_locations \
file=map_list.txt start="2012-01-01" increment="1 months"
t.vect.list random_locations
t.vect.export input=random_locations output=random_locations.tar.gz \
compression=gzip
t.vect.import input=random_locations.tar.gz output=new_random_locations \
basename=new_map directory=/tmp
