Introduction to Remote Sensing

Upon completion of this course, students would be able to: 1. give a description of the concept of obtaining information on objects from a distance without coming into contact with the object; 2. illustrate a historical evolution of Remote Sensing from the earlier period till date; 3. describe the physical basis for remote sensing; 4. identify the various remote sensing platforms; 5. differentiate between active and passive sensors; 6. identify the basic elements of photo interpretation; and 7. process digitally a satellite image and digitize some of the features.
