DEM产品分辨率是其质量和精度的重要表现.目前,关于DEM的分辨率研究,主要以实验方法或公式法进行分析比较确定区域DEM的最佳分辨率;这些研究对于具体应用具有一定的指导意义,但是对于DEM产品的分辨率确定往往引起了混淆.本文从地貌选取指标出发,对DEM产品分辨率进行分析研究,对其适用性的指导也有一定帮助.%DEM resolution is an important factor of quality and accuracy.At present,many methods are used in experimentation to make certain the optimal resolution of the area,which serves the guidance for the application but obscures the resolution of DEM product.The paper studies the resolution of DEM produc based on selection indicators of geomorphological structure,which is helpful for DEM applicability.
