Precision of the quasi-geoid for Qingcheng distriot,Qingyuan city

HONG Zhen-tian,TANG Li-ming,LIN Tie(Surveying and Mapping Institute Land and Resources Department of Guangdong Province,Guangzhou 510500,China)  
It's possible to get the geodetic height with the precision of 1 cm by GPS.If the quasi-geoid could be obtained with high precision,then the geodetic height can be transformed into the normal height with the same precision,and the GPS technique together with the quasi-geoid can be employed to substitute as the same leveling with high precision.The precision method of the quasi-geoid for Qingcheng distriot,Qingyuan city,is introduced in this paper,and then the quasi-geoid is analyzed and evaluated.The results show that the accuracy of the quasi-geoid can arrive at 1.3 cm.
