## 2. Now what?

This topic introduced basic definitions and conventions of directions and converting between angles and directions. *How* directions are used was not discussed. Combining directions with distances allows determination of complex areas and three-dimesional surface configurations. Most property surveys depend on distances and directions to define boundary extents.

*Traversing* is the traditional method of collection necessary measurements. Combining and reducing measurements in the traverse computation process includes direction determinations. This is covered in greater detail in the ** Traverse Computations** topic which builds on the concepts from this topic. Systematic procedures, mathematical checks, and typical errors are also discussed.
