This content shows the possibility and useful cases of night-time light data to assess disaster damages and recovery in post-disaster situations such as Hokkaido earthquake, dam eruption in Laos and Kerala flood in India. Moreover, how to browse and profiling night-time light on GEE are demonstrated here.
