// .NAME vtkDEMReader - read a digital elevation model (DEM) file
// .SECTION Description
// vtkDEMReader reads digital elevation files and creates image data.
// Digital elevation files are produced by the
// <A HREF="http://www.usgs.gov">US Geological Survey</A>.
// A complete description of the DEM file is located at the USGS site.
// The reader reads the entire dem file and create a vtkImageData that
// contains a single scalar component that is the elevation in meters.
// The spacing is also expressed in meters. A number of get methods
// provide access to fields on the header.
