Orthographic image is an important reference data source for the third national land survey, as well as the positioning benchmark and statistical basis of the national land survey, which determines the accuracy of the third national land survey results and the progress of follow-up work, and is also an important component of the third national land survey results. In order to ensure that the production of 1:10000 high-resolution orthophoto images meets the needs of the third national land survey work, and meets the relative requirements to the production of orthophoto products, it is really necessary to carry out quality control of orthophoto products.Based on the checking and accepting of 1:10000 orthophoto images at the national level, this paper discusses the quality control method of 1:10000 orthophoto products from the overall inspection. First of all, this paper studies and analyzes the key nodes of quality control in the overall inspection and clarifies the quality control requirements of each quality control key node;On the basis of carefully sorting out the typical problems found in the overall inspection of orthophoto products, carry out in-depth analysis of the causes and give corresponding solutions.This paper provides a technical reference for the quality inspection of other scale orthophoto products, and also provides a solution to the quality improvement of 1:10000 orthophoto products.
