AB  - Terrain factors can represent the basic features of a terrain surface, but it is difficult to accurately and specifically express the characteristics of the terrain using a single terrain factor. Therefore, various terrain factors can be comprehensively considered to describe the undulating changes of the terrain surface to a certain extent, which has a good effect.The data source used is DEM. From Geospatial Data Cloud（ http://www.gscloud.cn/search ）Obtained, concatenated multiple DEMs, cropped them using the vector boundaries of Gansu Province, and finally obtained the DEM data of Gansu Province.This dataset contains two types of terrain factors: micro terrain factors and macro terrain factors. Micro terrain factors include slope, aspect, slope change rate, aspect change rate, plane curvature, section curvature, comprehensive curvature, etc; Macro terrain factors include terrain roughness, terrain undulation, elevation variation coefficient, and surface cutting depth, totaling 11 types. The spatial resolution of the data is 30 meters, the data is in grid format, and the coordinate system is WGS84
