| Abstract: | Traditional leveling is one of the important methods of precision level measurement.Based on DiNi electronic level measurement data,the correct principles of unparallel to level surface and gravity anomaly are described of the multi valuedness for long distance and high precision level measurement of elevation.And applied in the adjustment calculation of second order leveling in a city,to prove the validity and necessity of the correction for precision level. |
