The Function of Traverses

Traverses are normally performed around a parcel of land so that features on the surface or the boundary dimensions can be determined. Often the traverse stations will be revisited so that perhaps three dimensional topographic data can be obtained, or so that construction data can be established on the ground. A traverse provides a simple network of 'known' points that can be used to derive other information. Large projects would normally not use simple traverses but instead multi-station networks with all intervisible stations having all data measured. This array of survey measurements needs a higher order of computation and analysis (and is dealt with in later year subjects), so is avoided at this stage.
