Abstract. The fundamental geographic national condition monitoring uses high-resolution aerial and aerospace remote sensing images to produce digital orthophoto images, land cover classification, geographical and national conditions, databases, statistical analysis and other results to monitor land changes within China's territory, the cycle is once a year. At present, the achievements have been applied in the fields of natural resource management, environmental protection and governance, people's livelihood guarantee, emergency disaster relief, and so on, it is of great significance to provide integrated, standardized and reliable geographic information products to meet the needs of ecological civilization construction. In view of the actual situation of the geographical conditions of the country, such as the organizational mode of production, the technical methods and the requirements of the results, this paper discusses the innovative development of the quality control method, the quality control content, the results quality evaluation and software development, etc. , having established a basic quality control system for monitoring the geographical conditions of the country, and applied it in the quality control work of monitoring the geographical conditions of the country carried out in the past four years from 2016 to 2019, effectively guaranteeing the quality of the results, it also provides reference and reference for other important engineering quality control work.
