NAME
t.rast.out.vtk - Exports space time raster dataset as VTK time series.
KEYWORDS
temporal, export, output, raster, VTK, time
SYNOPSIS
t.rast.out.vtk
t.rast.out.vtk --help
t.rast.out.vtk [-pcg] input=name directory=string [elevation=name]
[where=sql_query] [null=float] [--help] [--verbose] [--quiet]
[--ui]
Flags:
-p
Create VTK point data instead of VTK cell data (if no elevation map
is given)
-c
Correct the coordinates to fit the VTK-OpenGL precision
-g
Export files using the space time dataset granularity for equidis-
tant time between maps, where statement will be ignored
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog
Parameters:
input=name [required]
Name of the input space time raster dataset
directory=string [required]
Path to the export directory
elevation=name
Name of input elevation raster map
where=sql_query
WHERE conditions of SQL statement without ’where’ keyword used in
the temporal GIS framework
Example: start_time > ’2001-01-01 12:30:00’
null=float
Value to represent no data cell
Default: -99999.99
DESCRIPTION
This module exports all maps registered in a space time raster datasets
as VTK legacy files using a numerical numbering scheme. The VTK files
can be visualized with any VTK based visualize. Our preferred tool is
ParaView. The VTK legacy files are created using r.out.vtk.
EXAMPLE
In this simple example we create several raster maps with random values
and one elevation map. The random value raster maps are registered in a
space time raster dataset. All maps of this space time raster dataset
are exported using t.rast.out.vtk into the directory /tmp/export.
mkdir /tmp/export
t.rast.out.vtk input=precip_abs directory=/tmp/export/ elevation=elevation
ls -1 /tmp/export
