摘要
根据正形投影变形综合公式推算出能获得测区最小综合变形的高程抵偿投影面,进而建立地方坐标系,并指出采用该方法能有效的抑制测区的整体变形,但局部区域存在变形过大的现象。
This paper calculated the elevation compensating projection surface of minimum deformation measured areas based on conformal projection deformation comprehensive formula.Then established local coordinate system,and pointed out that using this method could effectively restrain the whole deformation of measured areas,but the local areas had excessive deformation phenomenon.
