Remote Sensing & Satellite Imagery. Messana Science 8. Warm Up. What is the picture to the right? What do you see in the picture? (Land Features, weather, etc..) How could this picture be useful? What is the location?. Remote Sensing.
Transmitted means the energy passes through an object.
Absorbed means energy is taken in by the object.
Reflected means energy bounces off of an object.
Example: When light strikes a leaf, red light is absorbed and green light is reflected. The green light enters your eye and that is what you see.Behavior of Light/ Energy
Satellites measure reflectance of different wavelengths in order to figure out what material the waves are hitting and create images of Earth (Spectral Analysis)
What determines the color you see when you look at someone’s shirt?
Satellites can not YET show very small images clearly (GROUND TRUTHING used)
Satellites can indicate elevation changes but can not show precise elevations (GROUND TRUTHING CAN)
