摘要
主要介绍了GPS工程的拟合的原理与方法,结合具体说明了GPS水准高程在大比例地形测量中的可行性,并对其方法的精度进行分析讨论,为以后GPS在地形测量中的运用提供了理论依据,为在地形测量中提高GPS的精度提出了相关政策。
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.
