New Geoid Model (GEOID12B) for Better Determination of Heights with Respect to Mean Sea Level

NGS produced a new geoid model, GEOID12B, to replace the previous GEOID12A model. GEIOD12B is a height transformation model for surveyors, engineers, and others involved in water flow and the determination of heights with respect to mean sea level. The geoid is a complex mathematical model used to measure surface elevations with extreme accuracy. GEOID12B is implemented in GPS manufacturer software. By providing a means for more accurate elevation determination, GEOID12B assists those involved in floodplain management, coastal and emergency response, port operations, and river/stream flow monitoring. In combination with GPS technology, GEOID12B makes more accurate heights obtainable anywhere in the United States.
