Jvgdata Vertical Curve

A vertical curve in the network shall be provided between track parts with different gradients in order to create a smooth transition. The minimum length of the vertical curve is 20 m, with some exceptions in connection with switches and crossings. Vertical curve is included as a trace element in the description of track geometry and is part of the profile geometry, which also includes slope. The track geometry represents the projected geometry and refers to the track center. The data product contains the radius of the vertical curve with characters (+ for convex and — for concave), length and the method used for the data capture. Since the geometry has the attribute Origin = G (measured geodetic), data is coordinated. The data product then has a high quality and can be used for all types of applications. The data product has stretch distribution and connects to the network with reference to the nearest previous node and nearest previous kilometre board with distance in meters to both the start and end positions of the vertical curve (=key points) in the direction of the track link.
