Unusual Displays of DEMs

  • J. Ronald Eyton

Abstract

Three procedures for producing new ways to visualize landforms as maps or images derived from Digital Elevation Models (DEMs) are given. One procedure is used to create a highly detailed circular gray scale image from an azimuthal distribution. A second procedure utilizes the principles associated with x-ray tomography for the construction of a volumetric map from DEM cross-sectional ‘slices’. The conversion of a DEM to a Digital Distance Model (DDM) comprises the third procedure, to provide ‘side-looking’ views of the DEM in a variety of map formats including stereograms. DEMs generated from Mars Orbital Laser Altimeter (MOLA) data were used to produce illustrations utilizing the three procedures.
