I want a streamlined Python-based workflow in Google Earth Engine that uses Sentinel imagery to both pinpoint flood-prone areas and track how each event evolves over time. Key tasks • Build an end-to-end script (Python API or Jupyter Notebook) that fetches, preprocesses, and masks Sentinel-1/2 data for my region of interest. • Generate clear water-extent maps for multiple dates, then derive cumulative layers that highlight historically flood-susceptible zones. • Produce time-series charts or simple dashboards to visualise flood progression during a chosen event. • Export final rasters/shapefiles and a concise README so I can reproduce the results locally. Please attach examples of past work in flood mapping, remote sensing, or Google Earth Engine so I can gauge fit quickly. Clean, well-commented code and straightforward instructions are critical; I’m aiming for a functional prototype rather than a polished, large-scale system.
