Using these satellite photos, the researchers mapped the following piece reflects the seriousness of various regions due to fire damage to a rough map, called the charred area reflectance classification (BARC). This map, the different shades of red indicate the severity of the fire, the color darkest area indicates the most serious fires.

Beijing time on September 12 news, the U.S. National Aeronautics and Space Administration Earth Observatory (NASA’s Earth Observatory) today announced a set of satellite images and mapping maps showing California “Silver Fire (Silver Fire)” the impact of the fire.

August 2013, when a major fire, California, USA – “Silver Fire” is not completely extinguished when the forest restoration experts have started their work. By analyzing satellite maps, the experts hope to identify those vegetation has been destroyed by fire, bare soil areas to focus on emergency repair.

U.S. Forest Service (US Forest Service) Fire District Emergency Response Team (BAER) staff into the fire area has just been extinguished. Their mission is to protect the reservoir, forest catchment areas and infrastructure from fire after flood damage. Staff at NASA’s Landsat satellites help find those areas of concern.

Below these two photographs were taken by satellites Landsat 8 shooting time were 16 August 2013 (upper) and May 28 (lower), showing the “Silver Fire” occurred in parts of California before and after. In this two pseudo-color photographs, scorched land rendered as red, green area of ​​forest or other vegetation; tan area is bare desert.

“Without BARC map, we can only by foot or by helicopter into the disaster area to assess the fire.” Forest Service remote sensing expert Carl Albury (Carl Albury) said, “maps can help staff determine they need to do thing and needs to go.

California “Silver Fire” burned 138,000 acres of land. Before the fire under control, Albury had already drawn some maps, so that staff work as soon as possible. BAER team using ground observation data for these maps calibration and adjustment, and then use them to plan forest restoration work.

“For forest restoration work is vital that time.” BAER team director Penny Luehring said, “In the southwest and southern California, fire season will start after four to six weeks of rain and caused flooding and if we want to control and mitigate influence of fire, we must act.
