| Abstract: | According to the calculation model of the Earth's gravity field parameters,this paper used global gravity field model EGM2008,with the object-oriented function of Microsoft Visual Studio 2010,designed and developed a calculation program.Which can calculate any point's gravity anomaly,height anomaly,components of deflection of the vertical? German Research Centre for Geosciences (GFZ) developed software verified the program's correctness.With the latitude and longitude data from cities in Jilin Province,the program calculated the corresponding gravity anomaly,height anomaly,components of deflection of the vertical. |
