| Abstract: | To explore the impact of the GPS /leveling points in the regional Quasi -geoid model , the paper proposed a weighted array model to establish regional Quasi -geoid model , which systematically introduced on the calculation process and the modeling methods , and used of high-level programming language C # programming to implement algorithms .According to a regional Quasi -geoid re-finement example to calculate and analysis it , the results showed that the use of the weighted array model to establish regional Quasi -geoid model is feasible , which can provide better protection for construction projects . |
