Instruments and Makers: Surveying and Geodesy:
http://americanhistory.si.edu/collections/surveying/
The surveying and geodetic instruments in the National Museum of American History reflect the importance of these activities in America since the first European colonists settled here some 400 years ago and turned the American landscape into property. With these instruments, and others of their ilk, Americans determined the limits of private and public lands, the paths of transport, and the boundaries of colonies, states, and nation. This site currently features a selection of over 300 museum objects relating to surveying and geodesy. The user may access the collection in the following ways: By makers, to view objects grouped by maker and to see selected biographies - by instrument, to view objects grouped by type and to read generic descriptions - or view a complete index of the objects on the site.

Historical navigation instruments illustrate the various ways that people have determined the location, direction, and speed of their ships at sea and in the air. Most of the instruments on this site were used by Americans engaged in commercial or military enterprises. They are housed in two bureaus of the Smithsonian Institution: the National Museum of American History and the National Air and Space Museum. The user may access the collection in the following ways: By makers, to view objects grouped by maker and to see selected biographies - by instrument, to view objects grouped by type and to read generic descriptions - or view a complete index of the objects on the site.
