| Abstract: | In the topographic mapping,we can use the proper fitting model to fit the GPS elevation.And this can be achieved with a traditional level measurement accuracy of elevation,not only to meet the mapping requirements,reduce the workload,but also greatly enhance the efficiency.This paper analyzed the accuracy of GPS height fitting and proposed recommendations to achieve better effect. |
