Infrared Aerial Photo is tool that is used to depict the changes in the environment. As seen above there are many different color that go into a infrared aerial photo. Lets start with the reddish colors, those seem to be paired with healthy or growing vegetation, the deeper and darker the color is the more dense it is. Next, there are like grayish green tones which are described as the dead or dying features. Above most all the area has red but you sure do see the green or tan to indicate that some of the crop or forest around there are not getting proper nutritions.
