Class EdgeSampling

java.lang.Object

com.graphhopper.reader.dem.EdgeSampling

public class EdgeSampling
extends Object

Ensures that elevation is sampled along a point list with no more than maxDistance between samples. Works by adding points along long edges and fetching elevation at each inserted point. For short distances this uses a simple linear approximation to interpolate between points and for longer distances it uses great circle interpolation.
