GEOS F493 / F693 - Geodetic Methods

Theory and application of modern geodetic tools to measure Earth's surface deformation with emphasis on GPS and InSAR. Data processing from raw data to kinematic products. Evaluation of signals and modeling of their sources. Applications range magma system characterization and analysis of slip during an earthquake to interseismic strain analysis and evaluation of changes in the hydrosphere such as glacial melt, seasonal precipitation effects and ground water level monitoring. Class includes 2 field trips to nearby sites early in the semester for GPS campaign deployments and data collection.

Linear Algebra (MATH 314), some programming experience (e.g., GEOS F436), or consent of instructor

No textbook required, but required readings will be posted on the class website / blackboard.

There will be approx. 6 homework assignments roughly every two to three weeks throughout the semester. Many of these assignments will require you to write code and produce computational results using MATLAB or Python (preferred). This software is available in the computer labs across campus or you may purchase a student copy of MATLAB (Python is free).

You will participate in weekly lab assignments. A lab report will be due at the beginning of the following lab period (except for the last lab, which will be due at the end of the week).

Graduate students will prepare and present a term project in the form of an expository term paper of roughly 10-12 pages. The topic of this project should be related to the course content and objectives and should involve some data processing, modeling and interpretation. You might apply techniques from the course to process, analyze and interpret data that you have gathered in your research, or you might choose one of the provided projects. If you choose thesis related work, it must be a new aspect; recycling of existing work is not permitted. Your topic must be approved by the instructor before you begin to work on it. After about 2/3 of the semester a complete the term paper is due. This version is graded on completeness, not correctness.

**Undergraduate Students:** Homework: 25%, Labs: 75%.

**Graduate Students:** Homework: 15%, Labs: 45%, Term Project 40%.

Grades will be assigned for each lab and homework assignment based upon assignment completeness and accuracy in the form of absolute scores. Final grade is average of individual exercise grades, weighted
as specified above. Unless otherwise noted, assignments will be due one week after they are assigned – they must be submitted prior to the beginning of subsequent lab period. Assignments are due electronically via blackboard. **Assignments will not be accepted late.**
There are no exams in this class.

I follow the University of Alaska Fairbanks Incomplete Grade Policy, which states that the letter "I" (Incomplete) is a temporary grade used to indicate that the student has satisfactorily completed (C or better) the majority of work in a course but for personal reasons beyond the student’s control, such as sickness, has not been able to complete the course during the regular semester. Negligence or indifference are not acceptable reasons for an "I" grade.
