摘要
大数据已在市政工程中得到了广泛应用,但大数据稀疏性和质量不高的问题亟待解决.为此,提出 1 种大数据质量评价方法,其中包括一级特征指标 7 项,二级度量指标 38 项和算术加权平均计算公式.地形图和BIM图库的实际案例验证说明,该方法可用、有效、正确,其对市政工程大数据质量评价实际应用具有一定的参考价值.
Abstract
Big data has been widely used in municipal engineering,but the problems of sparsity and low quality of big data need to be solved urgently.Therefore,a method for evaluating the quality of big data is proposed,which includes 7 primary characteristic indicators,38 secondary measurement indicators,and an arithmetic weighted average calculation formula.The practical cases of topographic maps and BIM libraries verify that the method is applicable,effective,and correct,and it has certain reference value for the practical application of big data quality evaluation in municipal engineering.
