Plane surveying is a type of surveying in which the earth is consider to be flat surface. Distances and areas involved are limited extent and ....

An error is defined as the difference between the .....

A line, known to be 150.000 meters long, is measured five times with a steel tape in the following order: 150.004, 149.998, 149.997, 150.005,and 149.996 meters, respectively. The more accurate of the five measurement is the

Five separate measurements were made of a line and their degrees of precision computed as follows in the following order: 1/5000; 1/2500; 1/6500; 1/7000; 1/10000, respectively. The measurement which is of a higher degree of precision was the one done in the

An early surveing instrument having an A-frame with a plumb line suspended from its apex and was used to determine the horizontal is the

Notes must not be crowded, and mistakes and omissions must be kept

to a minimum.

Ingenious instruments for surveying used for sighting

Ingenious instruments for surveyinga with 20-foot-long horizontal straightedge with supporting legs and a grooved top for water to serve as level.

First surveying equipment ever recorded.

This saves the surveyor time and effort from revisiting the site if something was not written down on the notebook.

Notes must be decipherable and understandable by all users, including those who haven’t been into the survey area.

This is the most important feature of a field note.

Notes should be suitable for every project and must be organized.

The person responsible, for the operation of all electronic equipment used in the survey.

The person responsible for the accuracy and speed

of all linear measurements with tape.

The person who checks all linear measurements made by the tapeman.

The person designated as the driver of the survey party, where a survey vehicle is used.

The person who keeps all records of sketches, drawings, measurements and observations.

Surveys used to determine ground features such as mountains,

hills, rivers, lakes, buildings, roads, ports etc.

Surveys used in determining the physical features and configurations of the land.

Surveys used to determine property lines and boundaries, corners and areas

Surveying used to carried out for area of >250 km

What is the position of the minimum party members in doing taping according to Curtis?

It helps the surveyor in keeping the tape horizontal while the tape is held off the ground.

It is a device attached to the zero end of the tape so that when a measurement is being taken, the correct amount of force or “pull” is being applied.

It is the easiest way of determining the distance between two points without the need of an equipment.

Drawback of measuring distances using pacing except one

It is equivalent to the distance either between your heels or your toes when you make two step.

A 45 meter course, AB on level ground was paced by a surveyor for each trial for the purpose of determining the pace factor. The number of trial taken are as follows: 50, 53, 51, 53, 52, 53. Determine the face factor of the surveyor in 3 decimal places.

A subtense bar is a tripodmounted bar with targets set precisely 2 meters apart. This technique is accurate at short distances, that is, less than

A stadia rod held at a distant point B is sighted by an instrument set up at A. the upper and lower stadia hair reading were observed as 1.20 and 0.80 m respectively. If the stadia interval factor is 99.98 and the instrument constant is 0.30, determine the length of

line AB.

The subtended angles were read on a 2-m long substense bar using a theodolite having a $$0\degree20'14"$$  angle. Compute the distance between the theodolite and the subtense bar.

A subtense bar is a tripodmounted bar with targets set precisely 2 meters apart. The targets are kept precisely 2 meters apart by the use of _______ under slight tension.

It consists of observing through the telescope the apparent locations of the two stadia hairs on a vertically held rod

Sources of Errors except two.

What do establihed darts in a dartboard mean?

A measure of dispersion or spread of a distribution

Normal Tension is defined as the applied pull which will lengthen the tape to equal the

Errors in tape that is always negative
