In the conventional land use remote sensing updating and interpretation process, there are some shortcomings such as lack of effective control omission and low efficiency of interpretation operation. In this paper, the relevant reasons are analyzed, and on the basis of practice, an optimized update interpretation process is proposed. In order to improve the concentration of interpreters and increase the automation of editing operations, the optimization process optimizes part of the routine process, especially the original comprehensive search process is optimized to split the land use layer by type and search the change by type, so as to solve the problem of missing judgment. At the same time, some necessary links are newly established, and some complicated manual operations are handed over to application software. The application practice shows that this optimized land use remote sensing update interpretation process not only simplifies the tasks of each link, but also improves the pertinence of understanding translation and the automation of operation, which helps to reduce the missing judgment and editing errors in the interpretation process. Although the interpretation process is increased, the overall interpretation time is reduced and the interpretation efficiency is improved.
