Next-generation Hill-shading analysis method for complex terrain

For projects with complex terrain, the most crucial step when selecting an available area is to find areas that meet the sunlight conditions. The conventional method for sunshine filtering typically follows the principle of not being blocked by other mountains from 9 am to 3 pm throughout the year. When the arrangement capacity is insufficient, the time range will be shortened. There are the following issues with this analysis method: 1. It can only conduct preliminary quantitative analysis of direct radiation, but cannot analyze the scattering and reflection losses caused by mountain obstruction; 2. For complex terrain, the sunshine periods of the mountains are not symmetrical, making it difficult to handle; 3. It is not possible to Analyze the occlusion loss outside the specified time period. The new generation of Hill-shading analysis method directly targets the ultimate goal of Hill-shading analysis, which is to select the areas that receive the…
