Several possibilities, although you are covering a great deal of
historical ground:
International Institution for the History of Surveying and
Measurement-- http://www.fig.net/hsm/index.htm
Early American Surveyors: Mapping the Wilderness--
http://www.profsurv.com/magazine/article.aspx?i=2038 (I mention this
online article because it was by Silvio A. Bedini, a deceased
scientific instrument historian at the Smithsonian (although he
retired in 1987 it may be that someone else there can point in a
relevant direction; Bedini also wrote _With Compass and Chain: Early
American Surveyors and Their Instruments_)
Jonkers, A.R.T., 2005. "Parallel meridians: Diffusion and change in
early-modern oceanic reckoning," in: Noord-Zuid in Oostindisch
perspectief, ed. J. Parmentier. The
Hague: Walburg, pp.17-42. (online at:
http://earth.uni-muenster.de/~jonkers/PARAMER.pdf; extensive notes)
Geomagnetism: Early Concept of the North Magnetic Pole--
http://gsc.nrcan.gc.ca/geomag/nmp/early_nmp_e.php (site maintained
by the Geologic Survey of Canada, with at least some mention of what
Mercator went through to develop his landmark 1569 world ma )
I would also suggest perusing the references available here:
