ESPM 5216 - Basic Geodesy

Syllabus

Class Zoom Meeting Room - where we'll meet if you have questions outside of class, email or call to set up an appointment, then click to join. 

Supplementary Text - Geodesy for Geomatics and GIS Professionals, 2nd ed., by J.A. Elithorp, Jr., and D.D. Findorff, ISBN 978-1-58152-658-5, available from XanEdu.com. This is a bit expensive, I suggest you check out the copies in the library if you can get them delivered; I'll be able to lend one copy, and can perhaps look for alternative sources. I'll cover relevant formulas in the lecture notes, you should borrow my or the library's copy to decide if you really need this book. Since we only do a partial read of the text, it might be best for most of you to use borrowed copies.
