>acc_val	      Acceleration value in percent of gravity of the
>                 polygon.  The polygon represents the range of
>                 acceleration values that are contained within its
>                 borders.  The polygon is assigned the lowest value
>                 allowed within the polygon's borders.  The range of
>                 values allowed within a polygon is controlled by the
>                 contours.  Valid values are:  0,4,8,12,16,20,24,28,32,
>                 36,40,60,80,100,120,160,240,320,400
>
>valley		A topological indicator that tells whether the area
>                 contained within the polygon is a local minima (valley)
>                 or not.  A value of "1" indicates the area is a local
