What is a curve calculation in route surveying?
Answer: Determining elements of horizontal and vertical curves for road and railway design
Road and rail design requires precise curve geometry.
What is a vertical curve?
Answer: A parabolic curve connecting two grades on a roadway profile
These curves provide smooth grade transitions in road design.
What is bearing-bearing intersection?
Answer: Finding a point location from bearings observed from two known points
Two directional observations from known points locate an unknown point.
What is a coordinate transformation?
Answer: Converting positions between different coordinate systems
Positions must sometimes be expressed in different reference systems.
What is the radius of curvature in route surveying?
Answer: The radius of the circle that defines a horizontal curve
Road curves are defined by the radius of an imaginary circle.
What is an inverse calculation in surveying?
Answer: Computing bearing and distance between two known coordinate points
Known coordinates yield the direction and distance between them.
