Abstract:
In this paper,fitting method of geoid was analyzed.A method and comparison of surface fittingwere presented,and the theory and method of interpolation were studied.The theory and method of quasigeoid numerical model were also studied.According to GPS location principle and geodetic theory,geoid refined theory and methods of Dahongshan Copper mining areaabout 20square kilometers area were studied.The geoid was determined byusing GPS/standard geometric method with GPSleveling data and the“remove restore”method of EGM2008 model.According to the actual situation in Dahongshan Copper Mine elevation,topographic change fierce,the known public point was calculated and compared.Point data were also checked.Height anomaly within range Dahongshan Copper was calculated.
Key words: quasi geoid, normal height, geodetic height, fitted model, EGM2008model
