They are listed as follows: Manual Method - Manual slope staking using a rag tape, fiberglass rod and level. Both methods involve marking various points on-site utilizing fixed elements like survey nails, cuts in masonry, checkerboard targets, etc., and then measuring the X, Y and Z values of those points. Land surveyors measure horizontal positions in geographic or plane coordinate systems relative to previously surveyed positions called control points, most of which are indicated physically in the world with a metal benchmark that fixes the location and, as shown here, may also indicate elevation about mean sea level (Figure 5.10).
