11 Define the size and shape of the earth Used as basis for coordinate systems Variety of models: - Flat earth - Spherical - Ellipsoidal WGS 84 defines geoid heights for the entire earth

Based on Geodetic Datum Describe locations in two or three dimensions (ie. X,Y,Z or X,Y) Local and Global Common systems Geodetic Lat, Long (global) UTM (local) State Plane (local) Variety of transformation methods
