| Abstract: | Using the GPS precise relative localization technology, gains the achievement of precise earth high, and associations measure the normally high of certain GPS point in the area by using the precise geometry fourth-leveling measure, Then uses these data achievement establishment corresponding mathematical model to carry on other spots the elevation fitting computation, in this process, Adopts unceasingly weakens and eliminates the quality of data, Thus obtains the elevation achievements satisfies fourth-leve... |
