摘　　要：本文研究了用EDM(电子测距)边长的精度估算方法;用等权代替法估算界址点最弱点的点位中误差;由坐标解析法界址点与面积的误差传播关系、导出了面积精度估算的具体计算公式。对于实际的房产面积精度的合理估算具有一定的现实意义和指导作用。This paper discusses the estimating method of side length surveying with EDM（electronic distance measuring）, applying the method of equal-weight substitution to estimate mean square error of the weakest boundary point. The practical formula for area of house property precision estimation is developed, from the relations of propagation between the analytical boundary points and the area. There must be guiding role and practical significance for precision estimating of actual house property area surveying.
