抽象的。来自遥感器的高分辨率红绿蓝（RGB）图像，例如飞机、无人机、卫星和国际空间站（ISS）上的图像，是实时应急响应应用的具有成本效益的数据源。我们描述了一个评估光谱行为进行评估的有效性，两个高分辨率的RGB图像数据集的洪水范围在密集的城市地区的映射和监测。该评估是卡尔加里2013年洪水事件案例研究的一部分。输入的图像包括非常高分辨率的航空照片和国际空间站上搭载的SERVIR环境研究和可视化系统（ISERV）获得的图像。结果表明，这两个RGB图像集的互补性，在提供有效的城市洪水实时响应映射。空间分辨率较高、大气影响较小的航空照片可以提供洪水分布的细节; ISERV-ISS图像可以提供洪水分布的时间变化。
Abstract. High-resolution red-green-blue (RGB) images from remote sensors, such as those carried on aircrafts, UAVs, satellites, and the International Space Station (ISS), are cost-effective data sources for real-time emergency response applications. We describe an assessment undertaken on spectral behaviors to evaluate the effectiveness of two high-resolution RGB image datasets for mapping and monitoring of floodwater extent in dense urban areas. The assessment was as part of a case study of the Calgary 2013 flood event. The input imagery included very high-resolution aerial photos and imagery acquired with the SERVIR Environmental Research and Visualization System (ISERV) carried on the ISS. The results demonstrate the complementary nature of these two RGB image sets in providing effective urban floodwater mapping for real-time response. The aerial photos with higher spatial resolution and less atmospheric effect can provide the details about the floodwater distribution; the images from ISERV-ISS can provide the temporal variation of floodwater distribution.
