62 This module exports all maps registered in a space time raster datasets
63 as VTK legacy files using a numerical numbering scheme. The VTK files
64 can be visualized with any VTK based visualize. Our preferred tool is
65 ParaView. The VTK legacy files are created using r.out.vtk.
66
68 In this simple example we create several raster maps with random values
69 and one elevation map. The random value raster maps are registered in a
70 space time raster dataset. All maps of this space time raster dataset
71 are exported using t.rast.out.vtk into the directory /tmp/test1.
