Course Objectives
This course focuses on the theory and methods of the generation, compilation, analysis, and applications of digital elevation data. Specific topics include GIS terrain data models, photogrammetry and LiDAR DEM processing, terrain surface modeling, digital terrain analysis, terrain visualization, and watershed delineation. The course includes computer exercises in the generation and processing of DEM using GIS and image processing software packages including ArcMap, ArcGIS 3D Analyst, ArcScene, Erdas Imagine and Leica Photogrammetry Suite (LPS).
Required: Li, Z., Zhu, Q, and Gold, C. 2004. Digital Terrain Modeling: Principles and Methodology. CRC Press.
Optional: Lillesand, T. M., Kiefer, R. W., and Chipman, J. W. 2004. Remote Sensing and Image Interpretation, 5th edition. John Wiley & Sons. (Instructors will distribute readings from this text.)
In addition, students will read articles
from peer-review journals. These articles are available in pdf format in the I:\Students\Instructors\Geoffrey_Duh\GEOG4593\Readings
folder. These articles are:
Baker,
M. E., Weller, D. E., and Jordan, T. E. 2006. Comparison of Automated Watershed
Delineations: Effects on Land Cover Areas, Percentages, and Relationships to
Nutrient Discharge. PE&RS 72(2): 159-168.
Peng,
M-H. and Shih, T-Y. 2006. Error Assessment in Two Lidar-derived TIN Datasets. PE&RS
72(8): 933-947.
There are several ESRI digital
books that will be used for both the theoretical and practical components of
the course. These materials can be found in several subfolders in the I:\Students\data\GIS\ArcGIS9.1_documentation\ESRI_Library
folder.
We will also use ERDAS Imagine
Field Guide. The document is available in I:\Students\Instructors\Geoffrey_Duh\ERDAS
Imagine.
Grading
The instructor will grade graduate and undergraduate students based on separate distribution curves. The components of a student’s grade are:
|
Class Participation |
10 % |
|
Midterm |
15 % |
|
Lab Assignments |
40 % |
|
Project |
35 % |
Class
Participation (10%) (Click here for the quiz schedule)
Attendance to this course is mandatory. If you miss more than
two class periods then you will be penalized five percent of your final grade
per absence. PLEASE DO NOT MISS CLASS. You are expected to take part in the
discussions and if you are not in class then you cannot. If you are repeatedly
late you will be given an absence. The labs are due by Thursday before class the week after they are assigned (see the course schedule
for the exact due dates). You can hand them in class or put them in my mailbox in CH424.
All students are required to select a
topic from a list provided by the instructor (see next page) and give a 10
minutes presentation on that topic to the class. You must prepare a powerpoint
presentation, 4 discussion/quiz questions and their answers. Students who are
responsible for the week’s topics must email the questions to the course
mailing list and the questions and their answers to the instructor by 5pm the
day before the class. The presentation should be mainly based on the assigned
readings. I strongly encourage you to put additional relevant materials you
find on the internet or from other references that might help students
understand the topic.
Exams (15%)
There will be
one in-class, closed-book mid-term exam and no final exam. Unscheduled in-class
quizzes will be administered without notifications. Results of these quizzes
will be counted toward class participation.
You will do practical exercises on the computers. If you do not finish the labs during the assigned time periods (usually every Thursday) the lab also has open hours. The practical exercises provide a way to acquire skills using GIS software packages and to apply the course concepts to real data. Lab exercises are due by the beginning of the next exercise. All exercises require a significant amount of time to finish. Make sure you pace your lab exercises appropriately to prevent from turning them in late. Please refer to the course schedule for specific due dates of the exercises.
A term project is required for all
students. The project should investigate a particular research problem using
the software packages that we use in class. You should acquire spatial data and
if necessary digitize the data and the project should involve some types of
digital terrain analysis. The deliverable is a digital copy of Powerpoint
presentation that you will present to the class. Individual graduate
students also Each project group
must submit a final paper that describes the project in a publishable
style/format (see guidelines here). There
are two stages to the project (the dates they are due are listed on the course
schedule):
Project
proposal: Submit a one page project
proposal. It should include a project title, a research question, a list of the
spatial and attribute databases you will use, and a conceptual description of
the methods you will use. Please make appointments with the instructor to discuss
your proposal if you have any questions. Here
is a list of criteria for reviewing a proposal.
Oral presentation: Includes the essential information described in the
proposal, data sets used, the analyses performed, and display the maps and
tabular output derived from the analyses (see
presentation rubric).
