Teaching Design of Generalized Adjustment Method for Surveying Adjustment
This paper analyzes the teaching reform achievements characteristics of the core course"Surveying Adjustment"in the surveying and mapping engineering major.It is pointed out that the applicability of generalized adjustment model and method has not been fully discussed in the teaching books and cases,especially for the adjust-ment problem with designing matrix of the deficiency rank.In view of this,this paper systematically discusses the so-lution of the generalized adjustment model,and obtains a universal parameter estimation method for the generalized adjustment model.Then,the binary boundary is broken between the observation and the initial data,and the role of evaluation and connections is clarified by weight.Finally,the decisive role on the form of generalize adjustment mod-el is analyzed through a simple case with different parameter selection scheme,and the unity and universality in both essence and form is revealed from the generalized adjustment model and its solution.
