  1. Chapter 0 Introduction Analysis and applications of remote sensing imagery Instructor: Dr. Cheng-Chien Liu Department of Earth Sciences National Cheng Kung University Last updated: 5 November 2014

  2. Syllabus • Course name: Analysis and applications of remote sensing imagery • Credit: 3 • Prerequisite: • Graduate students • Undergraduate students of the third or four year • Introduction to remote sensing • Digital image processing • Time: • Wednesday 13:10 – 14:00 • Thursday 10:10 – 12:00 • Place: • Remote sensing laboratory • Teaching Assistant:

  3. Objectives • Introduce students • The fundamental concepts of Analysis and applications of remote sensing imagery • The training in a commercial software (ENVI) of digital image processing • Students will learn • The techniques of enhancement and quantification of digital imagery acquired by remote sensing • Students are expected • Design and implement a practical project using techniques/knowledge learned from this course

  4. Textbook • Remote sensing and image interpretation, 5th edition, T.M. Lillesand, R.W. Kiefer and J.W. Chipman. John Wiley & Sons, 2004 偉明代理（成大圖書部可代訂） • ENVI Tutorials, 2003 edition, Research System Inc, 2003.

  5. References • Remote sensing, models, and methods for image processing, Robert A. Schowengerdt, second edition, San Diego, Academic Press, 1997. • Introductory Digital Image Processing: A Remote Sensing Perspective, John R. Jensen, second edition, Prentice Hall, 1995.

  6. Schedule • Introduction • Image rectification and restoration • Image enhancement • Image classification • Data merging and GIS integration • Hyperspectral image analysis • Scientific paper reading and term project report • SAR processing and analysis • Programming in ENVI

  7. Some questions • Who am I? • http://mail.ncku.edu.tw/~ccliu88/ • Why are we here? • You and I, … • Why exams? • Acquire knowledge, … • Why taking lectures? • Save time and efforts, … • Why Lab evaluation? • Keep on the right track, …

  8. Responses • Lecture notes on web • Three ways to be master of AARSI • Practice • Practice • Practice • Strategy • Free access to the remote sensing lab (issue entry card) • 10 min on-site test every week • On-site (mid-term and final) exams • Monitoring student’s progress and grade • On-line report everybody’s grade every week

  9. Grade • Weekly on-site exams 60% • Term project 40% • Base on at least one SCI paper • A short essay

  10. Laboratory Regulation • No computer games, MP3, pornography, DVD, movies or any illegal downloads • The computers are endued with the most noble mission of education • No food or drink • The computers are neither hungry nor thirsty • Take off shoes • The computers got a delicate respiratory system • No changes of hardware or software • The computers like the way they are

  11. Enforcement of Regulation • Those who have the privilege of using the lab have the responsibility to report any violation of regulation • Camera system • Computer log file • Laboratory head • Take in charge of this lab • Take all responsibilities

  12. Violation of Regulation • One violation, three points • Five points, revoke entry card • Stay with any violation without report, one point each • Penalty of losing or damaging entry card: NT 500
