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
