vertical reference system
- Definição1
- The vertical reference system is the datum to which the elevation values are referenced. Mean Sea Level (MSL) is the required vertical reference system. The Earth Gravitational Model (EGM-96) must be used as the global gravity model. If a geoid model other than the EGM-96 model is used, a description of the model used, including the parameters required for height transformation between the model and EGM-96 must be provided.

- Mean sea level (MSL) datum, which gives the relationship of gravity-related height (elevation) to a surface known as the geoid, shall be used as the vertical reference system.
