The Second Grade Leveling Densified Gravity Survey and Data Processing
In the second grade leveling work of Qinghai Province,due to the high average elevation and large elevation difference of the leveling line,the densified gravity survey was carried out.This paper analyzed the point distribution,observation and data processing methods of densified gravity survey on the second grade leveling line,and compiled a data processing program for densified gravimetry,which has a certain reference value for carrying out densified gravity survey in other regions.
