Detailed Description

read a digital elevation model (DEM) file

vtkDEMReader reads digital elevation files and creates image data. Digital elevation files are produced by the US Geological Survey. 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.
