Chapter 5: Land Surveying and GPS. 1. Overview. As you recall from Chapter 1, geographic data represent spatial locations and non-spatial attributes measured at certain times. We defined "feature" as a set of positions that specifies the location and extent of an entity. Positions, then, are a fundamental element of geographic data.

A theodolite is a surveying instrument that dates back to the 16th Century, and it's used to measure horizontal and vertical angles. Modern theodolites have a telescope that can be mounted to a swivel (which can move both horizontally and vertically), and the crosshairs allow you to make accurate alignments with the target object.

Traverse (surveying) Traverse is a method in the field of surveying to establish control networks. It is also used in geodesy. Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point. Traverse networks have many advantages, including:

The compass most used for forest surveying has a magnetized needle mounted on a pivot point and enclosed in a waterproof housing that has been graduated in degrees. The housing is attached to a sighting base with a mirrored sight. A hinged mirror lid allows you to look at the needle at the same moment you site your destination point.
