Static Methods

Bearing

double Bearing(CartesianCoordinate coordinate1, CartesianCoordinate coordinate2)

Summary: Calculates the initial bearing (forward azimuth) from one geographic coordinate to another. The bearing is the angle measured clockwise from true north (0°) to the direction of travel.

Parameters:
     coordinate1  -  The starting coordinate.
     coordinate2  -  The destination coordinate.

Returns: The initial bearing in degrees (0–360), where 0° is north, 90° east, 180° south, 270° west.

Bearing

double Bearing(double longitude1, double latitude1, double longitude2, double latitude2)

Summary: Calculates the initial bearing (forward azimuth) from one geographic coordinate to another. The bearing is the angle measured clockwise from true north (0°) to the direction of travel.

Parameters:
     coordinate1  -  The starting coordinate.
     coordinate2  -  The destination coordinate.

Returns: The initial bearing in degrees (0–360), where 0° is north, 90° east, 180° south, 270° west.

Distance

double Distance(CartesianCoordinate coordinate1, CartesianCoordinate coordinate2, DistanceMeasurementType measurement)

Summary: Calculates the great-circle distance between two geographic coordinates.

Parameters:
     coordinate1  -  The first coordinate.
     coordinate2  -  The second coordinate.
     measurement  -  The unit of measurement for the result.

Returns: The distance between the two coordinates in the specified measurement unit.

Distance

double Distance(double longitude1, double latitude1, double longitude2, double latitude2, DistanceMeasurementType measurement = Kilometers, double earthRadiusKm = 6371)

Summary: Calculates the great-circle distance between two geographic coordinates.

Parameters:
     coordinate1  -  The first coordinate.
     coordinate2  -  The second coordinate.
     measurement  -  The unit of measurement for the result.

Returns: The distance between the two coordinates in the specified measurement unit.

ToUtm

UniversalTransverseMercatorResult ToUtm(CartesianCoordinate coordinate)

Summary: To UTM.

Parameters:
     coordinate  -  The coordinate.

ToUtm

UniversalTransverseMercatorResult ToUtm(double latitude, double longitude)

Summary: To UTM.

Parameters:
     coordinate  -  The coordinate.

ToWgs84

CartesianCoordinate ToWgs84(UniversalTransverseMercatorResult utmResult, int maxDecimalPrecision = 8)

Summary: Converts a Atc.Math.GeoSpatial.UniversalTransverseMercatorResult back to a WGS84 geographic coordinate. This is a convenience overload that unpacks the fields from the result returned by Atc.Math.GeoSpatial.UniversalTransverseMercatorConverter.ToUtm(Atc.Structs.CartesianCoordinate) or Atc.Math.GeoSpatial.UniversalTransverseMercatorConverter.ToUtm(System.Double,System.Double).

Parameters:
     utmResult  -  The UTM result to convert.
     maxDecimalPrecision  -  The maximum number of decimal places in the returned latitude/longitude values.

Returns: A Atc.Structs.CartesianCoordinate containing the WGS84 latitude and longitude.

ToWgs84

CartesianCoordinate ToWgs84(int utmZoneNumber, string utmZoneLetter, double utmEasting, double utmNorthing, int maxDecimalPrecision = 8)

Summary: Converts a Atc.Math.GeoSpatial.UniversalTransverseMercatorResult back to a WGS84 geographic coordinate. This is a convenience overload that unpacks the fields from the result returned by Atc.Math.GeoSpatial.UniversalTransverseMercatorConverter.ToUtm(Atc.Structs.CartesianCoordinate) or Atc.Math.GeoSpatial.UniversalTransverseMercatorConverter.ToUtm(System.Double,System.Double).

Parameters:
