- Equate a standard surveyor's chain, or Gunter's chain, to 66 feet or 22 yards. There are also half-length chains of 33 feet. Equate an engineer's chain, or Ramsden's chain, to 100 feet. Divide a surveyor's chain into 100 links, equal to 0.66 feet, or 7.92 inches. Gunter's original chain was made with 100 links, a half-chain with 50. A Pennsylvania surveyor's chain, while 66 feet long, is made with only 80 links.

Surveying Units and Terms 1 The (square) arpent is a unit of area, approximately .845 acres, or 36,802 square feet.  Chain - Unit of length usually understood to be Gunter's chain, but possibly variant by locale. Chains equal to 2 poles (one half the standard length) are found in Virginia.

- Struve Geodetic Arc. The Struve Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through 10 countries and over 2,820 km.ll components of the Struve Geodetic Arc are linked to one chain and a number of the Arc sites belong to national state geodetic reference networks that confer integrity even with the geodetic measurements processed today.

Fundamentals Of Surveying Surveying is an important discipline in civil engineering that is intimately associated with a large number of facilities, including railways, roads, dams, bridges, and residential areas. Surveying creates the legal geographical boundaries and provides data for computer databases.

Surveying Units and Terms Gunter's Chain - Unit of length equal to 66 feet, or 4 poles. Developed by English polymath Edmund Gunter early in the 1600's, the standard measuring chain revolutionized surveying. Gunter's chain was 22 yards long, one tenth of a furlong, a common unit of length in the old days.

3. MEASURING DISTANCES 3. MEASURING DISTANCES. This section indicates, step by step, how to measure short distances, long distances, distances in tall vegetation and horizontal and vertical distances in steep sloping areas. To measure distances in a field (for example the length and width of a field), a chain or a measuring tape is used. Two men are required, the back man, holding the zero point of the chain (or the tape), and the front man, holding the other end of the chain.

Rod (unit) The rod or perch or pole is a surveyors tool and unit of length equal to 51⁄2 yards, 16 1⁄2 feet, 1⁄320 of a statute mile or one-fourth of a surveyor's chain and 5.0292 meters. The rod is useful as a unit of length because whole number multiples of it can equal one acre of square measure.

Chains to Feet Unit of length equal to 66 feet, used especially in the U.S. public land surveys. The original measuring instrument (Gunter's chain) was literally a chain consisting of 100 iron links, each 7.92 inches long.Steel-ribbon tapes began to supersede chains around 1900, but surveying tapes are often still called chains and measuring with a tape is often called chaining.he original measuring instrument (Gunter's chain) was literally a chain consisting of 100 iron links, each 7.92 inches long.

INTRODUCTION TO DISTANCE MEASUREMENT HORIZONTAL DISTANCE MEASUREMENT. In plane surveying, the distance between two points means the horizontal distance. If the points are at different elevations, then the distance is the horizontal length between plumb lines at the points. Pacing -- accuracy 1 / 100. Tacheometry (stadia) -- accuracy 1 / 1000. Taping -- accuracy (Standard) 1 / 5,000.

- Measure the distance to the nearest landmark along the centerline of the stream. = 125 feet. = 100 feet. 4250 ft –. 3000 ft = 1250 ft (Between Major Grid Lines). For this example, to measure 725 feet on this Profile, we. would count 5.8 “boxes” (725 ft / 125 ft = 5.8 squares). Therefore, the Minor Grid Line or “square”. measurement = 125 feet per “square” or “box”.

How to Calculate Chain Length Since that time, while the length of a fathom has been standardized to six feet, the measure between your hands is close enough. Pull 15 fathoms of chain (wear gloves while you do this). Fifteen fathoms of chain equals one shot.. Take the paint brush and paint one of the links in your right hand red.

Topographic Survey | Topo Survey The elevation or differences in elevation on the surface is usually shown as contours. A contour line is a line that connects points of equal elevation. There is usually a contour interval set, say 1-foot for conventional survey.An aerial topo survey may have a contour interval of 2-foot to 5-foot typically.Again, these contours are a way to represent the relative elevations of the surface of the land.uch like any other type of survey, a topographic survey, or topo survey for short, is done to locate natural and man-made features on a particular parcel of land.

Land Measurement A unit of length used in land surveys, named for the links of the chain formerly used by surveyors. There are 100 links in one (1) chain. One (1) link is equal to 0.66 feet, 0.04 rods, 0.01 chains, or 0.20 meters.nit of length on which the metric system of length measurement is based.

- We only had one previous step in this example so the distance measured is 12 plus 7.75=19.75 miles. If we had stepped the dividers two times before adjusting for the final measurement, the distance measured would have been 12 plus 12 plus 7.75 or 31.75 miles.o measure, set the dividers to a whole number, in this case we use 12, and walk the dividers along the line. The distance between the buoys is 24 nautical miles (two steps of 12 miles each).

How Big Is An Acre? Explained It is important to realise that an acre can be measured in any shape-from rectangles to circles or even hexagons-so long as the total area of land is 43,560 square feet. The most common shape for an acre is 1 furlong by 1 chain, or 660 feet by 66 feet.(. ). If you're struggling to get your head around just how big that area actually is, try visualising a soccer pitch, 75% of an American football field or 16 tennis courts in a 4x4 formation.he most common shape for an acre is 1 furlong by 1 chain, or 660 feet by 66 feet.

How to Calculate Chain Length As you prepare to lower your anchor, measure the length of the chain (called the scope of your anchor) by counting the number painted links, letting out a shot of chain for each 13 feet of water below your keel.: one painted link on the first, two painted links on the second, and three on the third.
