基于高分7号卫星DEM的坡度坡长计算精度评价

Shuitu Baochi Xuebao
[目的] 坡度和坡长作为重要的地形因子,其计算的准确性直接影响坡面土壤侵蚀模型的评价精度。高分7号卫星的高精度高程测量能力在地形因子的准确提取上具有较大潜力,期望能将其利用到坡度和坡长提取之中,实现对地形的准确表达。这需要对利用高分7号卫星DEM提取坡度坡长的结果进行精度评价。[方法] 利用地形因子(LS)计算工具,对陕西省吴堡县4个小流域高分7号卫星、1∶10 000地形图、激光雷达影像生成的DEM进行坡度、坡长的提取。采用相关系数(r)、相对偏差和绝对偏差作为评价指标,评价高分7号提取地形因子的精度。
