I'm searching for multi-spectral high resolution satellite images for flood events.
I found a database of flood events at the Dartmouth (Colorado) Flood Observatory with dates and approximate locations (polygons) and I used the Sentinel API hub to download images. The problem is that images cover too large an area and I cannot find the interesting regions; neither can I get images of the exact same location for two different dates (to compare pre and post events).
Is there a way to get a free dataset of high resolution satellite images for flood events (pre and post disater)?
BTW, I want to apply machine learning algorithms on these images.
