摘要
在GPS/水准网点的基础上,利用重力资料确定网区的高程异常走向,再利用各点的大地高和正常高求得高程异常,借此精确确定沿海地区局部的似大地水准面。
Based on the completion of GPS/Bench marks network, by using the gravity data to determine the trend of the height anomaly within the interest area, then deduce the anomaly through the ellipsoidal height and normal height, hence to refine the regional geoid.
