摘　　要：针对海岛(礁)DEM成果的特殊性和质量检验方法研究不足的现状,该文在分析传统方法的基础上,提出了一套适用于大批量海岛(礁)DEM成果质量检验的流程及技术方法:根据海岛(礁)DEM成果特征,分析了需要检验的质量元素,确定了不同质量元素的检验方法;进一步区分出可以采用程序自动检查的质量元素,并通过建立检查规则库,实现了部分检查项的批量自动检查;然后,研究其余质量检查项的实现方法,明确了内外业分工,完善了质量检查项的人机交互检查。最后,对3000余幅海岛(礁)DEM成果质量检验的结果表明:本文提出的技术路线可行,质量评价结果客观可靠。Aiming at the particularity of the products of coastal island （rock） DEM and the current status, that the method study of their quality inspection is insufficient, based on the analysis of traditional quality inspection methods of DEM data, the paper put forward a set of technical methods suitable for large quantities of the product quality inspection for coastal island （rock） DEM： data quality test index was researched according to the products of coastal island （rock） DEM quality model, and test method of the different quality index was discussed; quality index which can be tested by program was distinguished, and by establishing inspection rule library, the automatic batch check for section check items was realized; and then indoor and outdoor work was divided, which could improve the human-computer interaction method for check items. Finally, based on the quality inspection for more than 3000 pieces of the products of coastal island （rock） DEM, the result showed that the technical route proposed in this paper would be feasible with objective and truequality evaluation results.
