[vtkusers] How to import NASA SRTM DEM data into VTK

[Elvis Dowson]

Hi Mathieu,
                       So, if the size of the file is 2884802, then  
this implies that the sizeof(int) is 2 (which I'm assuming is the  
total number of bytes used to represent a signed integer. Since  
1201x1201 = 1442401.

Best regards,

Elvis Dowson
