摘要
从角规样地的动态估计方法入手,以角规样地与样圆的复合样地为例,对角规复合样地的动态估计方法进行研究和探讨,提出了两套估计方案,并结合示例对各种方法的优劣进行了对比分析。
Starting from the estimation of changes from point samples,the method for estimation of changes from point sample-based complex plots,which are composed of point sample plot andcircular plot,is studied and two schemes are presented.Finally,the advantages and drawbacks of allapproaches are demonstrated and comparative analysis by using an example is also carried out.
