EES 645: Remote Sensing and GIS (4)

Learning Objectives:

Satellite remote sensing is a powerful tool to acquire information about the surface of any object. Thus, the information obtained through satellite imagery can be used for geological mapping, monitoring of natural resources and climate and weather prediction. In this course, the theory of electromagnetic radiation, principles of spectroscopy, data acquisition systems will be discussed in details. Emphasis will be given on the different image processing techniques and preparation of digital maps from the satellite data.
