摘要

由于互联通信和成像技术的发展,绘制灾害地图和跟踪灾后恢复情况的能力大大增强。在这项工作中,我们展示了一系列评估也门萨那人道主义危机造成的损害和恢复过程的技术。特别是,我们利用可见光红外成像辐射计(VIIRS)日/夜波段(DNB),以750米分辨率产生全球照明水平的夜间数据。虽然以前使用VIIRS DNB数据集执行的几乎所有工作都使用每月或每年的复合数据,但我们开发了利用该数据源夜间可用性的新方法,特别是用于绘制照明变化的规模和程度,准确识别爆炸发生和照明条件变化的日期,表征停电模式,并在空间和时间上追踪夜间照明的恢复。对于每一种方法,我们都与公开可用的数据集进行比较,以验证我们观察的准确性。总的来说,这些数据仅在事件发生后1天即可获得,由此产生的分析对于灾难响应以及确定和跟踪恢复投资尤其有价值。

Mapping Disasters & Tracking Recovery in Conflict Zones Using Nighttime Lights
The capability to map disasters and track recovery thereafter has seen substantial enhancement from the development of connected communication and imaging technology. In this work, we demonstrate a series of techniques for assessing the damage and the recovery process from the humanitarian crisis in Sana’a, Yemen. In particular, we make use of the Visible Infrared Imaging Radiometer (VIIRS) Day/Night Band (DNB), which produces nightly data on illumination levels globally at 750m resolution. While nearly all work that has previously been performed using the VIIRS DNB dataset uses monthly or annual composite data, we develop novel methods that leverage the nightly availability of this data source, particularly for mapping the scale and extents of illumination changes, accurately identifying the day when bombing occurred and illumination conditions changed, characterizing electricity outage patterns, and tracing the recovery of nighttime lighting both spatially and temporally. For each of these methods, we compare with publicly-available datasets to verify the accuracy of our observations. In total, these data, available only 1 day after an event, and the resulting analyses can be especially valuable for disaster response as well as targeting and tracking investments in recovery.
