Activities


Objectives: Students will be able to

  1. demonstrate the existence of infrared radiation through Herschel's experiment.
  2. explain the types of radiation that are of high transmittance in remote sensing data.
  3. explain how the atmosphere absorbs, transmits, and scatters energy and how each are important in remote sensing.
  4. explain how digital information received from the sensors on a satellite is translated into an image.

Grade Levels: 7-12

Background Information:

Remote sensing is measuring the amount of electromagnetic energy that is being reflected. By determining the amount of electromagnetic radiation that is reflected, one can derive information about the object being surveyed from images acquired from remote sensing systems. The sensors on satellites will pick up wavelengths of radiation in a narrow range which includes visible light to near infrared radiation.

The activities included will cover the basic concepts behind remote sensing. In addition they will explain how digital information is received and then translated into an image.
