DEM34

       SUBROUTINE  DEM34 (NIN,NOUT)
 C$    (DEM34 - Orthographic Relief)
 C$    Demonstration for  the  orthographic relief  program.   The
 C$    surface shown is  related to the  surface of DEM30,  DEM31,
 C$    and DEM33,  by  the subtraction  of  the variable  Z.   The
 C$    objective is to locate points where that surface equals  Z.
 C$    Orthographic  relief  will  sometimes  aid  to  distinguish
 C$    depressions in a surface from protruberances.  Orthographic
 C$    relief contours are drawn in red over blue normal contours.
