| Abstract: | This paper studied GPS height transformation.Based on further research of the mathematic model and error sources of transformation,it developed GPS height transform system which has functions of data managing,choosing of transform model,calculating and assessing precision.For intuitionistic showing the height anomalies,the system has three-dimensional function.At last,it validated the reliability and feasibility of the system by calculating and analyzing of an example.The system can satisfied the users according to the practical condition of different surveying areas. |
