Infrared aerial photo

Infrared aerial photos are a good way to help distinguish land features based on temperature. These types of photographs document the change based on n objects temperature. A good way to utilize this is when you need to distinguish land from water. Since the land is generally warmer than  the surrounding water there will be a noticeable change in color between the two. This shows a deep water channel off Sacramento, California.
