By measuring the slope, the topographic features in the planning area, including the distribution of different landforms such as plains, slopes and steep slopes, can be intuitively understood. Slope data is one of the important bases for land space planning decisions. By measuring and analyzing the slope, the layout of various spatial elements such as cities, towns, transportation and water conservancy can be optimized, and the overall utilization efficiency of land space can be improved. Through reasonable layout of industrial development and strengthening of ecological environment protection, the sustainable development of the economy and society can be promoted.
