slash.navigation.common.Interpolation

public class Interpolation
extends Object

Computes interior points on the straight line (Luftlinie) between two positions, one every intervalMetres, excluding the two endpoints. Interpolation is linear in longitude/latitude: for short legs sampled only for an elevation profile a great-circle path is intentionally not used.

Method Details

interpolate

public static List<double[]> interpolate(double longitude1,
 double latitude1,
 double longitude2,
 double latitude2,
 double intervalMetres)

Returns the interior points on the straight line from (longitude1, latitude1) to (longitude2, latitude2), one every intervalMetres, as {longitude, latitude} pairs. The endpoints are excluded. Returns an empty list when intervalMetres <= 0 or the leg is shorter than two intervals.
