Surface grades are defined by two lines. The two lines define the right and left
edge of the surface grade. One of the two lines is used as the reference line.

Slopes, like surface grades, are defined by two lines. Different to surface
grades, only one edge of the slope, the hinge point, is known. The second
edge, catch point or daylight point, is defined by the intersection of the slope
and the natural surface. As the natural surface is unknown this edge can only
be staked out in the field. Finding and staking out the catch point is the most
important task when working with slopes.
