武汉和重庆市（2米以内）城市建成区、黑臭水体和河流分布图集（2019年）

2019年武汉和重庆市城市建成区、黑臭水体和河流分布图集，通过获取武汉市和重庆市的高景一号（0.5米）、高分六号（2米）等高空间分辨率遥感影像，对其进行融合、几何、大气校正等预处理；采用指数法结合目视解译提取城市建成区、城市河流矢量数据；在此基础上，根据BOI指数得到城市建成区黑臭水体遥感提取产品，并绘制专题图形成的图集。2019 Atlas of Urban Built-up Areas, Black and Odorous Water Bodies and Rivers in Wuhan and Chongqing. High-spatial-resolution remote sensing images (0.5 m resolution from Gaojing-1, 2 m resolution from GF-6) of Wuhan and Chongqing were collected as the data source. Preprocessing operations including image fusion, geometric correction and atmospheric correction were conducted on the acquired images. Vector datasets of urban built-up areas and urban rivers were extracted using the index method combined with visual interpretation. On this basis, remote sensing extraction products of black and odorous water bodies within urban built-up areas were obtained via the BOI index, and thematic maps were plotted to compile this atlas.
