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 equidistant 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 000000_tempmean_monthly.vtk 000001_tempmean_monthly.vtk 000002_tempmean_monthly.vtk 000003_tempmean_monthly.vtk 000004_tempmean_monthly.vtk 000005_tempmean_monthly.vtk 000006_tempmean_monthly.vtk 000007_tempmean_monthly.vtk 000008_tempmean_monthly.vtk 000009_tempmean_monthly.vtk 000010_tempmean_monthly.vtk 000011_tempmean_monthly.vtk
