[Paraview] large elevation data file

[Jack Gundrum]

Hi,

I have a LIDAR data file that is too large to load in ParaView.  I 
define it as a vtk file with the header

# vtk DataFile Version 2.0
elevation
ASCII
DATASET STRUCTURED_POINTS
DIMENSIONS 6060 6060 1
ORIGIN 0 0 0
SPACING 1 1 1
POINT_DATA 36723600
SCALARS elevation float 1
LOOKUP_TABLE default

ParaView blows up with an error vtkFloatArray: Unable to allocate xxx 
elements.

Should I partition the data file somehow to work with ParaView, or did I 
define the header info wrong?
Any ideas welcome.
