interface ICoordinateTransform in Tinman.Terrain.Georef

An ICoordinateTransform object provides a mapping from to map coordinates (i.e. easting and northing) to geodetic coordinates (i.e. latitude and longitude).

interface	ICoordinateTransform	extends	ICoordinateFlip
		base of	CoordinateTransform

Attributes

IsFlip

Does this coordinate system transform flip the handedness?

property	IsFlip { get }
type	bool
value		true if the coordinate system handedness if flipped, false if not.
inherited	ICoordinateFlip.IsFlip

Methods

Flags

Applies the given coordinate system flags to this transform.

method	Flags (CoordinateSystemFlags flags)
type	ICoordinateTransform
params	flags		The coordinate system flags to apply.
returns		[not-null]	The resulting coordinate transform.

Remarks:

The given flags will change the interpretation of easting and northing values that are passed to MapToGeographic or returned from GeographicToMap.

GeographicClip

Checks if the given coordinates lie within a bad region of this transformation.

[Pure]
method	GeographicClip (float64 latitude, float64 longitude)
type	bool
params	latitude		Latitude in radians, in terms of horizontal datum of geodata.
	longitude		Longitude in radians, in terms of horizontal datum of geodata.
returns			true if the given coordinates are considered to be bad, false if they are ok.

Remarks:

Bad regions are where heavy distortion or coordinate wrap-around occurs. This method is intended to be used for visualization. It should not be used for data processing.

GeographicToMap

Performs the forward calculation.

[Pure]
method	GeographicToMap (float64 latitude, float64 longitude)
type	Vec2D
params	latitude		Latitude in radians, in terms of horizontal datum of geodata.
	longitude		Longitude in radians, in terms of horizontal datum of geodata.
returns			The resulting easting (X) and northing (Y) values, in map units.

MapToGeographic

Performs the reverse calculation.

[Pure]
method	MapToGeographic (float64 easting, float64 northing)
type	Vec2D
params	easting		The easting coordinate, in map units.
	northing		The northing coordinate, in map units.
returns			The resulting longitude (X) and latitude (Y) angles in radians, in terms of horizontal datum of geodata.

Extensions
