摘要
本文从坐标转换参数的计算模型、WGS-84坐标的获取、已知地方坐标系坐标的检验、转换参数的计算等几个方面探讨了物探测量施工中WGS-84坐标到地方坐标系坐标转换参数的计算方法,并通过实例说明了检验已知地方坐标系坐标的必要性和转换参数的计算。
This article discusses the calculation method of transformation parameters from WGS-84 coordinates to the local seismic coordinate system by using coordinate transformation parameter calculation mode,by verifying the known coordinates under the local coordinate system,by confirming WGS-84 coordinates and by construction of the calculation model for the transformation parameters.Examples are illustrated to show the necessity of coordinate validation for the known local coordinate system and to show the best method to choose the proper transformation parameters for the seismic prospect.This can be helpful to surveyors.
