What is the purpose of taping in surveying?

Tapes are used in surveying for measuring Horizontal, vertical or slope distances. Tapes are issued in various lengths and widths and graduated in variety of ways.

What is tape plumbing in surveying?

Plumbing (of suspended tapes) Required when obstacles or surface irregularities make it undesirable to lay the tape on the ground. Tape is held in a horizontal position with a plumb bob over the point used to mark the tape length. Marking Tape Lengths.

What is EDM in survey?

Electronic distance measurement (EDM) is a method of determining the length between two points using electromagnetic waves. EDM instruments are highly reliable and convenient pieces of surveying equipment and can be used to measure distances of up to 100 kilometers.

How is taping distance measured?

When using a measuring tape, the distance between the two pegs can be read directly on the tape by the front man. When using a chain, the number of links between the two pegs is counted. The total distance is equal to the number of links multiplied by the length of one link (20 cm).

What is slope taping?

slope taping—Taping wherein the tape (or chain) is held as required by the slope of the ground, the slope of the tape measured, and the horizontal distance computed; slope chaining.

How many types of tape are there in surveying?

There are 5 types of tapes available in surveying for linear measurements and they are as follows : Linen Tape. Woven Metallic Tape. Steel Tape.

What are the errors in taping?

The last errors in taping is misalignment. If the tape is not in a straight line between the two points whose distance apart is being measured, then the error in the horizontal plane can be calculated in a similar manner to the error due to slope in the vertical plane.

What is BS and FS in surveying?

h) Back sight : (B.S.) – The first sight taken on a levelling staff held at a point of known elevation. B.S. enables the surveyor to obtain HI +sight i.e. Height of Instrument or line of sight. i) Fore Sight : (F.S.) – It is the last staff reading taken from a setting of the level. It is also termed as minus sight.

What is tape and its types?

The most common types of tape include masking tape, flooring tape, duct tape, electrical tape, packing tape, painter’s tape and double sided or mounting tape. Other types of tape have specialized applications, such as surgical tape, hazard tape and gaffer’s tape.

What are the used of measuring tape?

A tape measure, or measuring tape is a type of hand tool typically used to measure distance or size. It is like a much longer flexible ruler consisting of a case, thumb lock, blade/tape, hook, and sometimes a belt clip. A tape measure will have imperial readings, metric readings or both.

How are tape surveys used in land surveying?

Tapes are used in surveying to measure horizontal, vertical, and slope distances. They may be made of a ribbon or a band of steel, an alloy of steel, cloth reinforced with metal, or synthetic materials. Tapes are issued in various lengths and widths and graduated in a variety of ways.

What are the gradations on a surveying tape?

The most common surveying tape will have gradations in feet and hundredths of a foot. Often the even footmarks are in red with tenths marked in black numbers. The 0.05 gradation lines are usually longer than the hundredths (0.01) but shorter than the 0.10 marks. The end of the tape is another important item to inspect.

What are the last errors in taping in surveying?

The last errors in taping is misalignment. If the tape is not in a straight line between the two points whose distance apart is being measured, then the error in the horizontal plane can be calculated in a similar manner to the error due to slope in the vertical plane.

When do you use tape to measure distance?

The measurement of distance with the help of chain or tape is known as chaining. However the term chaining should be used for the distance measured with the help of chain, the term taping should be used when measuring distance with the help of tape. However the term chaining is still used for measuring distance either by tape or chain.
