NAME

       NNGETASPECTS - retrieve the aspect at a specified coordinate.

SYNOPSIS

       CALL NNGETASPECTS (I,J,ASPECT,IER)

DESCRIPTION

       I           (Integer,  Input) - A subscript indexing the first dimensioned variable in the
                   output grid of the most recent call to NATGRIDS.

       J           (Integer, Input) - A subscript indexing the second dimensioned variable in the
                   output grid of the most recent call to NATGRIDS.

       ASPECT      (Real,  Output)  -  The  slope at the grid point Z(I,J), where Z is the output
                   grid in the most recent call to NATGRIDS.

       IER         (Integer, Output) - An error return value. If IER is returned as  0,  then  no
                   errors  were  detected.  If  IER  is  non-zero, then refer to the man page for
                   natgrid_errors for details.
