    Subject: geodesy
    One 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:

    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.

    edition (1982). Each chapter has a list of references.
