What is the check line?

Definition of checkline : a hawser made fast on a dock and checked on a ship’s bitts and used when coming alongside a wharf for taking off way or snubbing toward the wharf.

What is a check line in surveying?

Check Line A check-line also termed as a proof-line is a line joining the apex of a triangle to some fixed points on any two sides of a triangle. A check-line is measured to check the accuracy of the framework. The length of a checking line, as measured on the ground should agree with its length on the plan.

What does base line mean?

Base line: It is the most important line & is the longest line. On the sides of main� lines the purpose measuring such lines is to check the accuracy within main station are located this lines are also known as group line. Tie line : a tie line is a line which joins subsidiary or tie stations to the main line.

What is base line in civil engineering?

In surveying, a baseline is a line between two points on the earth’s surface and the direction and distance between them. In a triangulation network, at least one baseline between two stations needs to be measured to calculate the size of the triangles by trigonometry.

What is the use of tie line in surveying?

Tie line joins two fixed points on main survey lines and it checks the accuracy of surveyinf as well as it helps in showing the details of the surveyed field.

What is tie station surveying?

Subsidiary or Tie Station These are the points selected on main line, where it is necessary to run auxiliary lines to locate interior details such as corner, tree, building etc. Lines joining tie station are called Tie Lines or Subsidiary Lines.

What are base line check line and tie line of chain surveying?

Answer: Check line joins the apex of main triangle with any fixed point on other two sides of triangles. It measures accuracy of the framework. Tie line joins two fixed points on main survey lines and it checks the accuracy of surveyinf as well as it helps in showing the details of the surveyed field.

What is a baseline questionnaire?

A baseline survey is a study that is done at the beginning of a project to collect information on the status of a subject (anything from crop yields to birth weights) before any type of intervention can affect it.

Why is Baseline Road called baseline?

The State Department of Transportation said its I-215 freeway offramp sign “Base Line Street” was so named because “The city of San Bernardino told us that was the name.”

What is Baseline and Meridian?

Baseline and Meridian – Imaginary lines used by surveyors in locating and describing land under the rectangular survey method. The north-south line is the meridian, the east-west line is the base line.

What is a tie line in phase diagram?

An isothermal (constant temperature) line through the alloy’s position on the phase diagram when it is in a two phase field, intersecting the two adjacent solubility curves, is called a tie line (yes, that’s the horizontal yellow line on the diagram).

What is a main station?

Main Station means a telephone that is connected directly to a central office and has a unique telephone number.

What is the difference between base line and check line?

Base line – Longest survey line passing through the centre of the are to be surveyed is called as base line. Tie line – Line joining some fixed points as a Tie station on the main survey line is called as Tie line. Check line – The line joining between the apex of triangle and some fixed point on survey line or on base line is called as check line.

What is the difference between base line and tie line?

Base line – Longest survey line passing through the centre of the are to be surveyed is called as base line. Tie line – Line joining some fixed points as a Tie station on the main survey line is called as Tie line.

What are the main check lines in railway system?

Check lines: These are the lines connecting Main station to a subsidiary station on opposite site are connecting to subsidiary station. On the sides of main� lines the purpose measuring such lines is to check the accuracy within main station are located this lines are also known as group line.

What is the difference between detail-line and Main-Line?

Main frame works of survey line are built on it. Detail-line: If the important objects are far away from the main lines, the offset formed is large, which reserve into inaccuracy and time consuming in the field work. In such cases the secondar lines are run by selecting station on main lines.
