Functions

open override fun along(line: LineString, dist: Double): LngLatAlt

Returns the point at a specified distance along the line.

open override fun bearing(a: LngLatAlt, b: LngLatAlt): Double

open override fun destination(p: LngLatAlt, dist: Double, bearing: Double): LngLatAlt

Returns a new point given distance and bearing from the starting point.

open override fun distance(a: LngLatAlt, b: LngLatAlt): Double

distanceToLineString

open override fun distanceToLineString(p: LngLatAlt, line: LineString): PointAndDistanceAndHeading

Returns an object of the form {point, index, t}, where point is closest point on the line from the given point, index is the start index of the segment with the closest point, and t is a parameter from 0 to 1 that indicates where the closest point is on that segment.

pointToSegmentDistance

open override fun pointToSegmentDistance(p: LngLatAlt, a: LngLatAlt, b: LngLatAlt): Double

Returns the distance from a point p to a line segment a to b.
