NAME

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

KEYWORDS

       temporal, import, vector, time, create project

SYNOPSIS

       t.vect.import
       t.vect.import --help
       t.vect.import   [-eoc]   input=name   output=name     [basename=string]     directory=name
       [title=string]     [description=string]     [project=string]     [--overwrite]    [--help]
       [--verbose]  [--quiet]  [--ui]

   Flags:
       -e
           Extend project extents based on new dataset

       -o
           Override projection check (use current projects’s CRS)
           Assume that the dataset has same coordinate reference system as the current project

       -c
           Create the project specified by the "project" 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

       project=string
           Create a new project (location) and import the data into it. Do not run this module in
           parallel or interrupt it when a new project 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
