The result of GPS elevation surveying is geodetic height, while normal height is widely used in practical engineering. Therefore, it’s meaningful
for
engineering to study how to translate the geodetic height into normal height. Gravity-model method, data fitting method, regional
quasi-geoid model method is usually used in elevation conversion. Meanwhile, regional quasi-geoid model, which can provide digital elevation datum for us, which has great significance to practical engineeri
