A Circular Curve is a segment of the circumference of a circle. Circular curves are assumed to be concave.

ATTRIBUTES:

Record Boundary ID

The Record Boundary ID is a foreign key which points to a record in the Record Boundary entity, where information about the Record Boundary can be found.

Domain: numeric
 
 

Radius

The Radius is the distance from the center of the curve to any point on the circular curve.

Domain: numeric
 
 

Central Angle

The Central Angle of a Circular Curve is the angle at the center of radius of a circular arc included between the radii, passing through the beginning and ending of the arc.

Domain: numeric
 
 

Direction

The Direction of a Circular Curve is defined as the direction the curve tends, as stationing along the curve increases.

Degree of Curve

The Degree of Curve arc definition is the central angle subtended by a circular arc of 100 feet. The Degree of Curve chord definition is the central angle subtended by a chord of 100 feet.

Domain: numeric
 
 

Long Chord Length

The Long Chord Length is the straight line distance connecting the beginning of the curve and the end of the curve.

Domain: numeric
 
 

Length of Curve

Length of Curve is arc distance of the Circular Curve.

Domain: numeric
 
 

Type of Degree of Curve

The Type of Degree of Curve is either the arc definition or the chord definition.

Domain: Arc, Chord
