Surveying and Surveying Instrument History

The expression that "Those who do not remember the past are bound to repeat it" probably comes from the experience of the Israelites in Egypt and their subsequent celebration of the Passover. However, it is applicable to all of the human race, and  the surveying profession is certainly not exempt.  It is in this spirit that I would like to start a discussion that relates to the history of surveying and surveying instrumentation.It is difficult to know where to start or…See More

"My personal research is on ancient Chinese surveying. It appears that by the 13th century BC the Chinese were making surveyor plats and that property was clearly defined on their bronze ritual vessels.     What would be the best book…"

"Rob, No, I realized you were trying to encourage the hiring of licensed surveyors....I was just trying to add another reason why a property owner should hire a surveyor. David"

Just a surveyor
Introduction to other Surveyors. One or more sentence Bio about your Relationship with Surveying
I now lecture and consult re: surveying, antique surveying instruments and surveying history...feel I can not only learn from others but also can help to mentor younger surveyors.
I have been involved with such projects as the Central Artery/Third Harbor Tunnel in Boston, the Seabrook Nuclear Station in Seabrook, NH, the Vernon Nuclear Station in Vernon, VT., the 10,000 acre Mount Washington Hotel/Bretton Woods Ski Area in the White Mountains of New Hampshire. I have been the Chief Surveyor for several firms in the Boston area, as well as owned and operated my own Surveying/Engineerin business in Colebrook, NH for 12 years. I have the strong opinion that many surveyors have become so enarmored with modern technology that they forget that there were millions of boundaries established before they were born; those boundaries cannot be re-established by us. They can only be redefined. Defining a boundary to the nearest 1/100th of a foot and 1 second of arc can give us an unwarranted confidence in our work, especially if we have moved the original boundary. We must learn Boundary Law and the rules of evidence at the same time we learn how to use the tools and instruments..the tools and instruments constantly change but the laws and rules regarding the locations of boundaries has changed very little since the early 1600's. New tools and instruments allow us to mathematically redefine boundaries...their use does not give us permission to change the location of a long established boundary! We older surveyors need to learn the new technology and at the same time pass on our knowledge and experience re" boundary laws and the rules of evidence.
