Abstract	General Relativity (GR) is at present the best available theory of gravity, as its predictions have been verified by all previously conducted experiments and observations. The technological capabilities for gravitational measurements on Earth and in its vicinity recently improved dramatically. Therefore, relativistic effects become increasingly important in modern geodesy. Although at present usually the first order post-Newtonian approximation of GR is sufficient, this may not be correct for specific applications and for future and contemporary high-precision geodetic measurements. We show how fundamental geodetic concepts such as the Earth's geoid and other reference surfaces, e.g. the reference ellipsoid, can be defined within GR. The overall framework is introduced and we give specific applications to various spacetime models.
