| Notes | uses data driven spatio-temporal modeling approach based on image acquisitions to approximate surface water. Process does take one-time setup time typically a 2-3 days. Algorithm code is open source https://github.com/Servir-Mekong/hydra-floods, processing platform is proprietary (Google) |
