To grasp the extent of California's wildfires, you must see them from space.

A NASA team has created maps using satellite data that show the areas most damaged by the Woolsey and Camp wildfires, the deadliest in state history.

Fires: There are currently 228 missing and 42 dead, making the northern fire even more deadly than the Griffith Park disaster of 1933. It virtually destroyed the city of Paradise. The Woolsey fire in the south has so far killed two people and damaged several seaside resorts. More than 300,000 California residents have had to flee their homes.

The cards: NASA's advanced rapid imaging and imaging team has created maps showing the areas most likely to be damaged by fires. The team used synthetic aperture radar images taken by the European Space Agency's Copernicus Sentinel-1 satellites, which are about 693 kilometers long.

What they show: The map above shows the extent of the Woolsey fire in southern California on November 11, covering an area of ​​50 km by 25 km. The color variation from yellow to red indicates damage to the soil surface. Maps are designed to help first responders identify areas of greatest need and prioritize how they affect resources. This is not the first time that NASA satellite data has been used for this purpose, but it may be the most urgent.
