A surveyor's compass, or a circumferentor is a device used in surveying to measure horizontal angles. It is used by directing the line of sight.
what the function of surveyor compass
Some careers, like sailing always use compass, but that depends on if the ship is employed to sail everyday.
A Surveyors Transit, a Protractor and a Brunton Compass are used for measuring angles for actual field work. Most commonly the first two are used because a Brunton Compass is not particularly easy to get your hands on. You can get one from a local geologist, but it can be difficult if you are new to the business or do not know the geoligist personally or know someone that does. This being said it is not imposible, but it is just harder. The Brunton Compass is easier and faster to use but it does not give quite as accurate of a measurement as a Surveyors Transit and a Protractor.
The compass you have is likely a vintage or antique navigational compass made by Keuffel & Esser Co. in New York. The ring around the compass is called a bezel, which is used for adjusting the direction. The key on the right side is a locking mechanism to hold the needle in place while not in use. This type of compass was commonly used by explorers, surveyors, and engineers for navigation and land surveying.
Local attractions such as buildings or metal objects can affect the accuracy of a prismatic compass survey by causing magnetic interference. This interference can lead to errors in compass readings and, consequently, inaccurate survey measurements. To minimize these effects, surveyors should identify and account for local attractions during their surveys, employing techniques such as taking multiple readings and using a declination correction.
They use pen and paper or laptops to record data.
