摘　　要：自2016年开始,地理国情工作的重心由普查转移到监测上来。地理国情监测地表覆盖分类数据成果的各项质量指标均比普查时更严格,如何更好地做好地表覆盖分类数据质量控制工作,直接影响监测数据成果的质量水平。本文结合山东省2019年度国情监测数据成果验收工作,对地表覆盖分类数据成果质量问题进行分析探讨,并对提高地表覆盖分类数据的质量水平提出建议。Since 2016,the focus of geography national condition has shifted from survey to monitoring.All the quality indexes of the results of surface coverage classification data monitored by geographical conditions are stricter than those of general survey.How to do a better job in quality control directly affects the quality level of the results of monitoring data.In this paper,based on the results acceptance of monitoring data of national conditions in Shandong Province in 2019,the quality problems of surface cover classification data are analyzed and discussed,and suggestions are put forward to improve the quality level of surface cover classification data.
