Abstract

Flood mapping is an essential component of planning flood mitigation. The availability of remote sensing data makes rapid flood mapping possible. This article develops an accurate method for rapid flood mapping using satellite imagery. Sentinel-2 imagery was tested by acquiring data before and after a flood event in a lowland area. Flooding extraction was performed using the newly developed Flood Inundation Extraction Index (FIEI) and compared to the Modified Normalized Difference Water Index (MNDWI), the most commonly used index. Based on the choice of threshold, the results are divided into flooded and non-flooded areas. Evaluation of the performance accuracy based on the total and kappa coefficients showed that the FIEI approach is more accurate than the MNDWI approach.

基于开源遥感数据的洪水测绘，使用高效的波段组合系统

洪水测绘是规划防洪的重要组成部分。遥感数据的可用性使快速绘制洪水地图成为可能。本文开发了一种利用卫星图像快速绘制洪水图的精确方法。哨兵2号图像是通过获取低地洪水事件前后的数据进行测试的。洪水提取是使用新开发的洪水淹没提取指数（FIEI）进行的，并与最常用的指数修正归一化差值水指数（MNDWI）进行比较。根据阈值的选择，将结果分为淹没区和非淹没区。基于总系数和kappa系数的性能准确性评估表明，FIEI方法比MNDWI方法更准确。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
