1)What would an image look like from a color and contrast aspect after displaying only the thermal band without enhancement?2) using thermal imagery - does water change temperature during the day? If so when is it usually the warmest? 1)What would an image look like from a color and contrast aspect after displaying only the thermal band without enhancement?

Explanation / Answer
1.
Remote sensing sensors are used to find variety of features of Earth’s environment like snow covered ice caps, sandy deserts, ice sheets, variation in water, and tropical rain forests. These surface features exhibits reflectance of the infrared radiations. Using infrared radiations we can detect surface feature, if the surrounding objects has high tempera than target object, then the target abject look white in color. The range of values of brightness present in a scene is referred to as contrast. The image of water looks blue in color without enhancement of thermal band due to the short reflectance of the infrared radiation.
2.
Yes, the slight variation of the temperature we can observe from day to night because of the change of heat of the water.
