sealed class

ProjCoordinateTransform

extends

CoordinateTransform

Public / Attributes

IsFlip

Does this coordinate system transform flip the handedness?

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

Public / Constructors

ProjCoordinateTransform

Creates a new instance of ProjCoordinateTransform.

public constructor	ProjCoordinateTransform (string projDef)
params	projDef	[not-empty]	The PROJ.4 definition string.

Public / Methods

Flags

Applies the given coordinate system flags to this transform.

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

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]
public virtual 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.
inherited	CoordinateTransform.GeographicClip

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]
public override 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.
implements	CoordinateTransform.GeographicToMap

MapToGeographic

Performs the reverse calculation.

[Pure]
public override 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.
implements	CoordinateTransform.MapToGeographic
