.SH 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 \fBr.out.vtk\fR.
.SH 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 \fBt.rast.out.vtk\fR into the directory
\fB/tmp/export\fR.
