摘　　要：基于实测数据,构建了海洋测深网检核指标的计算模型,结合海道测量规范要求,对测深网某些定性指标实现了定量计算,构建了海洋测深网数据质量评估指标。实际算例表明,检核指标的计算模型能够有效地反映数据的质量,有助于实现数据评估的标准化与规范化。Some index models for the quality evaluation of bathymetric data acquired in grid pattern are brought forward.According to hydrographic criterions,some qualitative indexes have been modeled for quantitative calculation,and hence some indexes are given out for evaluating the quality of sounding data.By experimental results,it is shown that the models work well in calculating accurately the quality indexes of sounding data and do help to standardize the job to evaluate data quality.
