When scientists want to view the Earth’s physical characteristics, they use Remote Sensing to collect images using special cameras. When these cameras are placed on satellites, they can be used to collect information on temperature changes in the ocean. Sonar installed on ships can photograph the ocean floor. Cameras on high-flying planes and satellites can take remote sensed pictures of large forest fires and map them from space. They can also track cloud movement to predict the weather or watch erupting volcanoes and dust storms. There are two types of Remote Sensing. With active sensing there is a time delay. The emission and return of images is measured by determining the speed, location, and direction of an object. RADAR and LIDAR are examples of active sensing. Passive sensing has the sensors gathering radiation emitted or reflected by a certain object. Reflected sunlight is the most common source of radiation measured by passive sensors. Other examples are film photography, infrared, and radiometers.
