Riparian Sun Map Line

Points created along lines representing river banks are categorized as Critcal, High, Medium, or Low in potenial to provide shade based on the aspect of the point in relation to the centerline of the river. The point were then converted to continuous lines with the same values as the points.沿表征河岸的线条生成的点位，将根据其相对于河道中心线的方位，按遮阴潜力划分为严重（Critical）、高（High）、中（Medium）、低（Low）四个等级。随后将这些点位转换为保留对应等级数值的连续线条。
