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
t.vect.import imports a space time vector dataset archive that
was exported with
t.vect.export.
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.
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
