Geodesy at Texas A&M University - Corpus Christi.   An undergraduate class intended as an introduction to the subject.

 

 

 

—>  Undergoing reorganization and rejuvenation <—

 

My favorite definition of geodesy: "Geodesy is a science dealing with the size, shape and gravity field of the earth in its three-dimensional time-varying state." Also see: https://en.wikipedia.org/wiki/Geodesy

 

I retired after a > 30 year career as a geodesist with a U.S. federal agency. During my last assignment I began teaching the undergraduate-level course in geodesy at the Texas A&M University-Corpus Christi (TAMUCC) as an adjunct. I continued to do so after retirement. 

 

This was an in-person class. Lectures prepared for the course (GISC3325) are linked here: Course Content (not maintained since 2013).

 

Note that the course was US-centric including extensive use of US National Geodetic Survey (NGS) data and resources. It did not provide much in the way of physical geodesy content.

* This site was originally developed to support an introduction to geodesy course delivered at TAMUCC. I stopped teaching the course after the 2013 Spring Semester. Neither it nor I am any longer associated with TAMUCC. I left the title unchanged to maintain continuity.
