Method Detail

getSlopeCosts

public static SlopeCosts getSlopeCosts(org.locationtech.jts.geom.CoordinateSequence elev,
                                       boolean slopeLimit)

Parameters:

elev - The elevation profile, where each (x, y) is (distance along edge, elevation)

slopeLimit - Whether the slope should be limited to 0.35, which is the max slope for streets that take cars.

Returns:

slopeSpeedCoefficient

public static double slopeSpeedCoefficient(double slope,
                                           double altitude)

getPartialElevationProfile

public static PackedCoordinateSequence getPartialElevationProfile(PackedCoordinateSequence elevationProfile,
                                                                  double start,
                                                                  double end)

parseEleTag

public static Double parseEleTag(String ele)

checks for units (m/ft) in an OSM ele tag value, and returns the value in meters
