NAME
t.vect.import - Imports a space time vector dataset from a GRASS GIS specific archive file.KEYWORDS
temporal, import, vector, time, create locationSYNOPSIS
t.vect.import
t.vect.import --helpt.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.
