Here's how to use the Sentinel-1 Explorer to run a change detection of radar images captured on different dates to determine the extent of wildfires. In this example we'll isolate the Park Fire, in Northern California. You can also do this for any change event, like flooding, deforestation, urbanization, oil spills, or shipping vessel movements. The radar imagery library goes back ten years so historical events can be tracked down too.
