【Abstract】 The paper introduces the theory of GPS-leveling,formula and the way of realization.It emphasizes discussing the theory and realization of calculating height anomaly by way of GPS leveling and precision level-surveying data,so does buildingthe system transformation model,solving the problem of being short of replicatedata between two systems.The example shows that the effect of using system transformation for calculating height anomaly is effective and the model can improve the precision of pre-existing height anomaly.更多还原
