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]    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_$i n=500 restrict=boundary_state@PERMANENT
           echo map_$i >> map_list.txt
       done
       t.create type=stvds temporaltype=absolute \
                output=random_locations \
                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 \
                     compression=gzip
       t.vect.import input=random_locations.tar.gz output=new_random_locations \
                     basename=new_map directory=/tmp
       t.vect.list new_random_locations
