Survey

Surveying plays a key role in the development of our physical environment. We need accurate surveys and maps to build roads, houses, schools, plus to locate our natural resources and our boundaries, locally or nationally.

Surveying observations are usually made with instruments levelled by means of spirit bubbles. Since these bubbles follow the influence of the earth's gravity the observations are made relative to the geoid.

Survey information may well be in the form of angle and distance measurements. Although there are GIS which can store and manipulate such geometric measurements, they are most often processed to derive Cartesian co-ordinates.
