t.vect.import1grass

Usage

Keywords

temporal, import, vector, time, create project

Overview

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.

Examples

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
