Course Objectives

introduction to the physics of remote sensing and its platforms, how to sensing

energy interaction with earth surface features, how the data will acquire and explaining the process of acquired data.

Course Outcomes

at the end of the course the student will able to learn to Select the type of remote

sensing technique / data for required purpose, Identify the earth surface features from satellite images, Analyze the energy interactions in the atmosphere and earth surface features and Perform corrections and process digital satellite data.
