“一步测量”中 ,为了检核及提高碎部测量的精度 ,需要对已构成附合或闭合条件的加密图根点或测站点进行平差 ,然后由平差后的图根点或测站点对所测碎部点进行改正 ,再通过数字测图软件成图 .这一系列工作可在外业测量结束后 ,用计算机在室内进行自动平差和自动改正 .本文介绍了其外业操作及内业处理的步骤和方法 In the “one-step measurement”, in order to check and improve the accuracy of the measurement of the shredding parts, an adjustment must be made to the root point of the encrypted map or the station site that has formed the attached or closed condition, and then the adjusted root point or station point The measured broken part of the point to be corrected and then through the digital mapping software mapping.This series of work can be measured in the field after the end of the computer with automatic adjustment and automatic correction in the field.This paper describes the field operations and internal Industry processing steps and methods
