Abstract: As an important spatial data in the unified natural resources survey and monitoring system, the land cover achievement will play a fundamental supporting role for all kinds of natural resource survey and monitoring projects. Hence, data quality of the land cover achievement will be related to the correctness and reliability for the statistics, analysis and evaluation results of various natural resources. According to the practice of quality control of major survey and mapping projects, to ensure the quality of the final achievement, it is important to formulate scientific, reasonable and unified quality evaluation criterion for the achievement, and conducts comprehensive, efficient and accurate data quality inspection on the achievement. This paper analyzes current situation of quality inspection and evaluation for the land cover achievement in some typical ongoing natural resources survey and monitoring projects, such as the geographical conditions monitoring project and the national land survey. Furthermore, this paper discusses uses quantitative index evaluation method for the quality evaluation criterion, using latest intelligent remote sensing image information extraction technologies for quality inspection of the classification accuracy, and uses latest remote and enhanced field verification method for the field quality inspection of the land cover achievement, which can provide technical references for quality control of the unified natural resources survey and monitoring.

Key words: land cover achievement, natural resources survey and monitoring, geographical conditions monitoring, land survey, quality evaluation, quality inspection
