| Abstract: | In this paper a method for determination of quasi Geoid in survey zone using artificial neural network is proposed, a architecture and algorithm of neural networks are also given. The accuracy of quasi geoid determined by this method is investigated in a survey area, the results show that the accuracy is about the order of 3cm, it is compared with method of fitting quasi geoid using quadric polynomial, and it is better. |
