Abstract

This short communication discusses how a specific geoarchaeological remote-sensing (RS) method, such as analyzing satellite images through NDWI (Normalized Difference Water Index), can be used to aid in searching and locating persons missing in watercourses. Thanks to its high capacity to analyze changes in the surface water area, this index can remotely detect the presence of anomalies related to disappearances in water bodies and provide valuable information that can reduce the use of human resources and help pinpoint likely areas of search. Two real-life cases of missing persons in rivers in which the NDWI index was used are presented, and the results obtained are discussed, emphasizing the importance of NDWI analysis as a complementary method to different approaches, especially non-invasive and remote-sensed ones, when positively searching for missing persons.
一种寻找水中失踪人员的互补遥感方法:两个案例研究
这篇简短的通讯讨论了一种特定的地质考古遥感(RS)方法,例如通过NDWI(归一化差水指数)分析卫星图像,可以用来帮助搜索和定位在水道中失踪的人。由于具有分析地表水区域变化的高能力,该指数可以远程检测水体中与失踪有关的异常情况的存在,并提供有价值的信息,可以减少人力资源的使用,并帮助确定可能的搜索区域。本文介绍了两个使用NDWI指数的河流失踪者的实际案例,并对结果进行了讨论,强调了NDWI分析在积极寻找失踪者时作为不同方法,特别是非侵入性和遥感方法的补充方法的重要性。
