The determination of optimum DEM resolution is helpful to improve the accuracy of the research results. The classification of DEM resolution based on topographic factor is studied. This paper classifies and expounds DEM resolution determination method from four aspects of "micro topographic factor", "macro topographic factor", "micro and macro composite slope topographic factor" and "slope topographic factor extension factor", which provides reference for the quantitative determination of optimal DEM spatial resolution in the future.
