I stumbled upon a few interesting books that you may find as interesting as I have. These books will be particularly interesting to geodetic surveyors and those surveyors across the planet who annually participate in Survey Earth in a Day. Flat- Earthers may find them to challenge their theories.
Sec. I. Historical -- sec. II. The oblate spheroidal hypothesis
Another great book worth checking out.
