A brief summary of a lecture

       Today, we listened to a lecture, Remote Sensing of wildfires, which was given by Tim Warner, a professor in the West Virginia University. The lecture is about the remote sensing  applied in the wildfires areas.

     The speech was started with the background of himself. From his experience,

 we can get a lot of information about some early remote sensing devices at the South Africa mining Company, such as B&W monitor, Color monitor, laser film writer, Film Cartridge. . .

     Then he introduced us the background of the Remote Sensing of wildfires and some Remote Sensing method, which is to use spectral radios(different things have different spectral wavelengths). He also gave us a spectral reflectance curve. From the graph, we can easily get the relationship between the reflectance and wavelength. There is also a key word, spectral band, only black light can be shown in the chart. Finally, he divided the theme into three parts, pre-fire(before), during fire and post-fire(after). Pre-fire is about fire fuel load mapping, we can know the fuel resource under the ground. During the fire, we can see the smoke, fire perimeter and hot spot from the images by mapping active fires. Post-fire(after) is a burn severity mapping, we can know which areas are suffering from the fires badly while which areas are low demaged by the fire.

      He also gave us some images by different devices. RGB can give us colorful images while NDVI vegetation index only can show black and white images. And the a brief introduction to WorldView-3(WV-3), the first civilian satellite with high spatial resolution(7. 5m)shortwave infrared imagery. He also gave us some research questions and the answers. We can know that short wave infrared is very important.

      After this speech, I knew a lot about remote sensing of wildfires and remote sensing can do such a lot in one area, it also can do some big in more and more different areas. There is so much for us to learn and discover.
