    Re: Longitude by calculator -theodolite
    From: Richard B. Langley

    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:
