Last comment.. The Introduction to Geodetic Astronomy in your UNB link is more advanced than my Mackie reference. The Mackie book covers the basic tools used (theodolite). I do have two books by one of your UNB reference authors. Mueller’s book entitled “spherical and practical astronomy as applied to geodesy”, this book is hair splitting in comparison to Mackie’s book. The instruments discussed in Mueller’s book are rare and expensive, the Wild T4 for example.

by calculator -theodolite
Subject: geodesyOne who practices it: geodesist But many professional geodesists don't know how to take or reduce theodolite measurements. ;-) On the other hand, surveying (or geomatics) engineers (should) know how to obtain precise and accurate results from a theodolite (or a total station). Don't forget, we have a lot of relevant (oldish but still relevant) publications for free download here:http://gge.unb.ca/Pubs/LectureNotes.html -- Richard Langley On Thursday, July 4, 2013,185, at 9:42 AM, G Becker wrote: > Hello:> > I decided to start this as a new topic.
