A compass is used to obtain angle measurements, while a chain or tape is used to calculate linear measures. Probably the most favored land grid system for its ease of use is the PLSS (Public Land Survey System), known by a couple of other names: STR (Section Township Range) & Jeffersonian (as in Thomas). Contours allow you to see the height and shape of mountains, the depths of the ocean floor, and the steepness of slopes.
