    Re: Resolution of systematic error

    Once again, google books.  This time "Plane Surveying", John Clayton
    Tracy, 1911.  Page 333 describes Lehmann's method in the chapter on
    plane-table surveying. (An interesting topic of its own.)

    Went looking for this, couldn't find anything downloadable that matched all 3 of those parameters. If you have access to it could you email a scan or a copy of page 333?

    Reading the description, it would seem the method has little bearing
    (sorry) on the az-intercept method.  It appears to deal with az errors
    while our issue is interecept (range to a surveyer) uncertainty.

    I am not sure what "our issue" means - my understanding is that the current subject is the resolution of systematic error?
