摘要
本文从误差理论的角度,探讨了面积量测过程中,控制面积的精度与分区数目n之关系为:m_(?)=m(n^1/2),从而得出了通过控制分区数目n,来达到提高面积量测精度之目的。同时设计了线状地物两边扣除的辅助用表,以使面积汇总工作的顺利进行。
From the error theory point of view, the article goes further into the relation between controling area precision and the number n which the areas are divided into in the process of area measure: That is M_(?)=M n^(1/2), So the precision of area measure can be improved by controlling the number n. Meanwhile the book of supple mentary forms is designed, which can be used to deduct the both side areas of the linear surface feafures, So that the job of totalling areas can be carried out smoothly.
