How many different types of plane table surveying exist?
There are four techniques to scan a plane table. They are resection, intersection, radiation, and traversal. While the other two are used to locate plane table stations, the first two are used to locate details.
Which of the following is not a tool used to establish correct angles?
An optical staff is a unique instrument. The optical square is a tool that consists of a spherical box with three slits. A box frame mounted on a pole serves as the cross staff. The optical square has been upgraded to become the prism square. Two telescopes at a 90° angle make up the site square.
How many different primary level types are there?
The four most common levels are as follows. There are four of them: the tilting level, the wye level, and the dumpy level.
A line's direction in relation to a specific meridian is referred to as:
In relation to a specific meridian, the bearing of the line indicates its direction. Any angular measurement tool can be used to determine its angle.
In a system with reduced bearings, bearing is gauged from:
In a reduced bearing system, the bearing is calculated from the closest point in either a northward or southward or counterclockwise orientation. It seeks to find the closest bearing.
How many different compass kinds are employed in surveying?
Prismatic and Surveyor's Compasses are the two compass kinds used in surveying. The most popular type of prismatic compass is used for surveying.
In the direction of the survey, a bearing is measured.
The term "fore bearing" is used to describe the angle that was measured in the direction that the survey was moving. Back bearing is the measurement of the angle perpendicular to the survey's forward motion.
Plane table materials include:
A well-seasoned hardwood component is the plane table. On top, a smooth surface is provided once it has been polished. A tripod can be attached to the middle bottom section through threading.
An offset is the measurement of an object's distance from the survey line.
Offsets are measured parallel to the survey lines. They utilize an offset rod to identify the locations of items and the lateral distance between them.
What number of different types of leveling staff are there?
Target personnel and self-reading employees are the 2 groups. Direct reading from the instrument through the telescope is possible for self-reading staff. A moving target against which readings are to be taken makes up the target staff.
A sighting device is used to locate an object.
Alidade is a straight edge with a sighting aid of some kind. Telescopic or plain (with slits) are both viable options. It is kept on a table that is level, and everything are seen.
One method is plane table (PT) surveying.
Objects are observed and noted as drawings (lines) on paper when surveying is done graphically. The line indicates the object's angular and station distance.
Originally, Dumpy level was created by:
The Dumpy level was created by Gravatt and consists of a telescope that is attached in two collars using adjustable screws.
The following is determined by a leveling staff:
A leveling staff is a rectangular rod that is straight and has graduations with zero at the foot of the staff. A horizontal line of sight from a level is made after it is positioned at the necessary spot.
The number of links in Gunter's chain is .
Gunter's chain, often known as the surveyor's chain, is 66 feet long. It has 100 links that are each 0.6 feet long. One mile is equal to 80 Gunter's chains.
In how many different chain kinds is chain surveying used?
There are 5 different kinds of chains that can be used for chain surveying. The metric chain, the Gunter's chain, the engineer's chain, the revenue chain, and the steel band or band chain are among them.
