t.vect.importgrass - Online in the Cloud

PROGRAM:

NAME

t.vect.import - Imports a space time vector dataset from a GRASS GIS specific archive
file.

KEYWORDS

temporal, import, vector, time

SYNOPSIS

t.vect.import
t.vect.import --help
t.vect.import [-eoc] input=name output=name [basename=string] directory=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 exported with
t.vect.export.

NOTES

Optionally a base map name can be provided to avoid that existing vector 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 single 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-imported.
db.connect -d
for i in `seq 1 5` ; do
v.random output=map_$i n=500 input=boundary_state@PERMANENT
echo map_$i >> map_list.txt
done

title="Random locations"
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

t.vect.import input=random_locations.tar.gz output=new_random_locations
