Detailed Course Description

This course serves as an introduction to remote sensing of the Earth with emphasis on geology. The course will introduce various instruments used to measure the Earth surface characteristics, describe the remote sensing data and their analysis. We will start with an overview of the basic concepts of remote sensing and digital image manipulation and analysis. Then we will introduce the properties of electromagnetic waves and describe the way they interact with solid surfaces in the visible, near-infrared, thermal infrared, and micro-wave regions of the electromagnetic spectrum. The last part of the course will cover the basics of radar imaging and an introduction to SAR interferometry. Hands-on experimentation with satellite images will familiarize students with digital images manipulation, including image enhancement, filtering, and registration to a geographic system. Digital topography data will be used for 3-D surface analysis. We will explore various regions of the world providing experience with terrain type identification and classification, tectonic structures recognition and mapping.

Course Structure

The course will meet twice a week: Lectures will be on Mondays in room 3645 of the Geology building and interactive lab sessions will take place on Wednesdays in our department computer laboratory located in room B703. Each week the lab assignment will be started during the lab hours on Wednesdays, completed as a weekly homework and returned on the following Wednesday.

Grading

1/3 Labs & homework assignments
1/3 Mid-term Exam
1/3 Final Exam

Prerequisites

Basic knowledge in electromagnetics (Physics 1B or equivalent) is recommended. Lab exercises are run on PC-Linux computers and some familiarity with computer environments is expected.
