The high resolution black and white (Panchromatic) satellite image below shows the location of forest cut blocks, roads and a power line right of way. The burn areas are not clearly evident using this data alone, however...
... the burn areas can be revealed by the color, or multispectral, imagery utilizing the satellite's infrared sensors to detect variations in vegetative cover such as tree foliage. The multispectral sensors provide a lower resolution ground sampling that helps when covering a large area, but which restricts one's ability to zoom in close.
By combining the high resolution panchromatic image and the information on vegetative cover from the multispectral image, we can best define those areas affected by fire. Note the reddish areas along the right side of the lower right cut blocks. The damage caused by this fire can now be rapidly evaluated and better managed.
