【Abstract】 The height offered by GPS receiver is the geodetic height above the WGS-84 ellipsoid,but our country uses normal height at present.We must convert geodetic height to normal height in order to make use of the GPS height in engineering application.In this paper,a method for converting GPS height to normal one by means of support vector machine is proposed,and compared with the methods of neural network,polynomial fitting etc.Tested by the real case,we get some helpful and useful conclusions.更多还原
