| Abstract: | 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. |
