Detailed Description

Converts WGS latitude-longitude coordinates to ENU local tangential east-north-up coordinate system.

Construct an LLToENUConverter instance with a reference point which will be used as the origin for the converted ENU coordinates.

Constructor & Destructor Documentation

◆ LLToENUConverter()

Cogs::LLToENUConverter::LLToENUConverter	(	double	latitude,
		double	longitude,
		double	altitude = `0.0`
	)

Constructs a new LLToENUConverter.

This converter will treat the given position as the reference point (I.e., the origin in the ENU plane) for conversion. All converted points will be relative to that origin. *============================================================================================

◆ calcVectorBetweenCoordinates()

glm::dvec2 Cogs::LLToENUConverter::calcVectorBetweenCoordinates	(	double	lat1,
		double	long1,
		double	lat2,
		double	long2
	)		const

Calculates a vector between the two geodetic points in ENU space.

◆ convert()

glm::dvec3 Cogs::LLToENUConverter::convert	(	double	latitude,
		double	longitude,
		double	altitude = `0.0`
	)		const

Converts the given latitude/longitude/altitude coordinates into local tangent plane ENU coordinates where X represents East, Y equals North, and Z is the height above the plane.

It should be noted that an altitude of 0.0 will result in coordinates that sit below the ENU plane. I.e., on the surface of the earth, so the further the point is from the origin, the further down it will be. *============================================================================================
