LSIT Mathematics for Surveying 2

Question 1

What is a curve calculation in route surveying?

Accepted Answer

Determining elements of horizontal and vertical curves for road and railway design

Answer

Road and rail design requires precise curve geometry.

Question 2

What is a vertical curve?

Accepted Answer

A parabolic curve connecting two grades on a roadway profile

Answer

These curves provide smooth grade transitions in road design.

Question 3

What is bearing-bearing intersection?

Accepted Answer

Finding a point location from bearings observed from two known points

Answer

Two directional observations from known points locate an unknown point.

Question 4

What is a coordinate transformation?

Accepted Answer

Converting positions between different coordinate systems

Answer

Positions must sometimes be expressed in different reference systems.

Question 5

What is the radius of curvature in route surveying?

Accepted Answer

The radius of the circle that defines a horizontal curve

Answer

Road curves are defined by the radius of an imaginary circle.
