Satellite Change Detection
Before/after satellite comparison of the same area on two dates from NASA GIBS true-color imagery (MODIS or VIIRS, about 250 m per pixel): one side-by-side JPEG with date labels plus pixel-based change metrics (share of changed pixels, brightness change) and a cloud, haze and snow estimate for each date, with a plain-language reading that says whether the change is likely real or just weather.
