Complex underlying surface water body identification method and black and odorous water body prediction method

The embodiment of the invention provides a complex underlying surface water body identification method and a complex underlying surface black and odorous water body prediction method. Spectral difference and temperature difference of water and background information in the target area are fully considered; combining the road information map, the land utilization information map, the multispectralremote sensing image and the thermal infrared remote sensing image of the target area, the water body distribution information in the target area is identified, and information such as asphalt roads,black roofs and combustion traces is excluded from the obtained water body distribution information, so that the identification result is more accurate, and the black and odorous water body is accurately predicted on the basis. 本发明实施例提供了一种复杂下垫面水体识别方法及复杂下垫面黑臭水体预测方法，充分考虑了目标区域内水体和背景信息的光谱差异以及温度差异，结合目标区域的公路信息图、土地利用信息图、多光谱遥感影像以及热红外遥感影像，识别出目标区域内的水体分布信息，得到的水体分布信息中排除了柏油公路、黑色的屋顶、燃烧痕迹等信息，使识别结果更加准确，并在此基础上准确预测出黑臭水体。
