| Abstract: | With the social and economic growth,the world science and technology are developing rapidly.In recent years,GPS has been fully accepted by the people with its increasing application.Therefore how to perfect the application of GPS elevation to large scale terrain survey has become the primary concern of topographic staff in the survey.This paper mainly introduces the GPS project fitting principle and method combined with its feasibility and accuracy in topographic survey,which serves as the theoretical basis to improve the precision of topographic survey. |
