Méthode	Description
CalcBoxByDistFromPtDEG ( double lat, double lon, double distDEG, SpatialContext ctx, Rectangle reuse ) : Rectangle
CalcBoxByDistFromPt_deltaLonDEG ( double lat, double lon, double distDEG ) : double	The delta longitude of a point-distance. In other words, half the width of the bounding box of a circle.
CalcBoxByDistFromPt_latHorizAxisDEG ( double lat, double lon, double distDEG ) : double	The latitude of the horizontal axis (e.g. left-right line) of a circle. The horizontal axis of a circle passes through its furthest left-most and right-most edges. On a 2D plane, this result is always from.getY() but, perhaps surprisingly, on a sphere it is going to be slightly different.
Degrees2Dist ( double degrees, double radius ) : double
Dist2Degrees ( double dist, double radius ) : double	Converts a distance in the units of the radius to degrees (360 degrees are in a circle). A spherical earth model is assumed.
Dist2Radians ( double dist, double radius ) : double	Converts a distance in the units of radius (e.g. kilometers) to radians (multiples of the radius). A spherical earth model is assumed.
DistHaversineRAD ( double lat1, double lon1, double lat2, double lon2 ) : double
DistLawOfCosinesRAD ( double lat1, double lon1, double lat2, double lon2 ) : double
DistSquaredCartesian ( double vec1, double vec2 ) : double
DistVincentyRAD ( double lat1, double lon1, double lat2, double lon2 ) : double
NormLatDEG ( double lat_deg ) : double	Puts in range -90 <= lat_deg <= 90.
NormLonDEG ( double lon_deg ) : double	Puts in range -180 <= lon_deg <= +180.
PointOnBearingRAD ( double startLat, double startLon, double distanceRAD, double bearingRAD, SpatialContext ctx, System.Point reuse ) : System.Point
Radians2Dist ( double radians, double radius ) : double
ToDegrees ( double radians ) : double	Same as {@link Math#toDegrees(double)} but 3x faster (multiply vs. divide). See CompareRadiansSnippet.java in tests.
ToRadians ( double degrees ) : double	Same as {@link Math#toRadians(double)} but 3x faster (multiply vs. divide). See CompareRadiansSnippet.java in tests.
VectorBoxCorner ( double center, double result, double distance, bool upperRight ) : double[]
VectorDistance ( double vec1, double vec2, double power ) : double	Calculate the p-norm (i.e. length) between two vectors
VectorDistance ( double vec1, double vec2, double power, double oneOverPower ) : double	Calculate the p-norm (i.e. length) between two vectors
