Class GraphElevationSmoothing

java.lang.Object

com.graphhopper.reader.dem.GraphElevationSmoothing

public class GraphElevationSmoothing
extends Object

This class smooths the elevation data of a PointList by calculating the average elevation over multiple points of that PointList.

The ElevationData is read from rectangular tiles. Especially when going along a cliff, valley, or pass, it can happen that a small part of the road contains incorrect elevation data. This is because the elevation data is coarse and sometimes contains errors.

This can lead to incorrect ascend, descend, and distance calculation of a route.
