摘要
城市建筑密度在研究城市内涝的过程中与城市不透水率分布情况紧密相连,它还是城市发展规划的一个重要指标。通过使用Suomi-NPP/VIIRS夜间灯光影像,结合GIS手段分析了2012年南京市主城区灯光图像强度值与建筑密度之间的关系,并建立了相应的建筑密度估算模型,结果表明VIIRS夜间灯光强度数据具有实现建筑密度估算以及其他社会经济数据空间网格化的巨大潜力。
Urban building density and urban impervious ratio are closely related. Urban building density is also an important indicator of urban development planning. Based on night lights images of Suomi-NPP/VIIRS and combined with GIS tools, the relationship between the light intensity and building density of 2012 is analyzed and established a model for building density estimation. The results showed that the nighttime light intensity data of VIIRS have great potential for achieving space grid data of building density and other socio-economic elements.
