【摘要】 数字化地籍测量中,利用控制点进行定向操作时容易出现错误。如果定向出现问题,将导致该站所测的界址点均出现错误。本文根据不同的错误类型,推导出了不同的数学模型。有些定向错误可以通过数学模型修正,有的错误类型则无法修正,当尽量避免。更多还原

【Abstract】 In digital cadastral survey,it is easy to occur errors when use control point does orientation operation.Orientation errors lead to mistakes of all feature points on local surveying station point.Different math models,corresponding ways to solve were given according to different types of errors in this paper.Some errors can be corrected by using math models,some can’t.For the errors that can not be corrected should be avoided.更多还原
