[Paraview] dem data

[Amy Squillacote]

Hi Jack,

Are you just trying to see your data as a height field rather than as a 
2D image? If so, then once you have your image data loaded into 
ParaView, apply the "Clean to Grid" filter to it (to convert it to an 
unstructured grid), and then apply the "Warp (scalar)" filter to convert 
the scalar values to height.
