Objective

This course will introduce the principle and application of remote sensing on aquatic environment. It will emphasize optical remote sensing applied to fresh and coastal water environment at land-water interface. We will start from introducing general remote sensing principles and image pre-processing. Then we will focus on understanding and characterizing the underwater light field. In the last third part of the semester, we will read, discuss and practice the important topics of remote sensing application on aquatic environment.

Prerequisite       

Introductory RS is preferred. The instructor will consider to approve the enrollment of individual students who doesnít have intro RS background.

Arrangement

The courses are composed of lectures, assignment/computer lab, student presentation, and topical discussions.

ENVI 5.4 will be used in labs. Attendance to class and is mandatory. Students are also expected to use extra time to complete assignments and submit on time.Assignments should be submitted through Moodle in WORD or PDF format.

All students are required to complete a Final project individually. You are encouraged to define the objective of your project, collect all necessary data and perform spatial analysis. A final report is due on the last day of final week.

Policies               

1.     Attendance to the class is required in the normal circumstances. Failure to meet course requirements due to illness will require documentation for alternate arrangements to be made. It is the responsibility of the student to obtain any materials (i.e. notes) from other students in the event the student cannot attend class for some reasons.  

2.     All exercises must be turned in by the hours the exercises are due.  Each student has one chance of late submission (no later than one week following the due date) during the semester. Other late submission up to 7 days after deadline without advance permission by the instructor will cause a grade deduction by half. No lab assignment will be accepted after one week following the due date.

3.     Missing sensor presentation, leading topical discussion, final project presentation, final project report, or >=2 homeworks will result in an F for the course.

4.     In general, students are encouraged to use lab computers to avoid any problem caused by personal computer setting. Instructor is not responsible to solve or troubleshoot the problems on your self-owned computers.

Grading: Assignment 35%, Sensor presentation 10%, Lead discussion 10%, Class participation 5%, Final Project 40%
