    Re: Longitude by calculator -theodolite
    From: G Becker

    Hello:

    I decided to start this as a new topic. My goal is to see how precisely I can determine my location using my theodolite (read scale to 3 seconds of arc).

    Thank you.

    Bruce

    Bruce,

    This is one of my favorite subjects. Listed below is a good reference which can be downloaded from the NOAA website. The Navlist has a resident Geodist*, so I'll attempt to not comment on this subject.

    1.) Manual of Geodetic Astronomy : Determination of Longitude, Latitude, and Azimuth by Albert Hoskinson and J Duerkesen, Special Publication No 237. In the preface of this book, beginning on page IX, it lists the reference material which also can be downloaded from the NOAA website. Most can be found in various Appendixes of the Annual Report of the Coast Survey.

    2.) If you want to purchase a book.. The Elements of Astronomy for Surveyors by J B Mackie. This book has been reprinted many times, I have the 8th edition (1982). Each chapter has a list of references.

    3.) Geodesy by Alexander Clarke. ( http://books.google.com/books?id=ECUJAAAAIAAJ&source=gbs_navlinks_s ) Most "geodesy" books reference this one.

    * I'm not sure if Geodist is the current politically correct term for a person who geodeticals.
