"Guide to Using Emergent Value-Added Products (EVAP) Module with QGIS for Disaster Response" by Taiwan Space Agency

In accordance with Sentinel Asia's strategic plan to empower local agencies with local data and Value-Added Products (VAPs) for addressing local needs, the Taiwan Space Agency (TASA) has developed a manual to facilitate the application of the EVAP module. This manual provides step-by-step instructions on how to utilize the EVAP module within QGIS to swiftly and easily identify disaster-affected areas.
