IDatumTransform

Description

interface Tinman.Terrain.Georef.IDatumTransform

Derived from: ISerializable
IEquatable<IDatumTransform>
IConfigurableNull
ICoordinateFlip
Extended by: DatumTransform ^abstract

A IDatumTransform transforms geographic coordinates from one datum to another one (horizontal and/or vertical).

Public / Methods

Append

public method Append → (1)

other ⁱⁿ : IDatumTransform: [not-null]
The datum transform to append.
returns → IDatumTransform: The resulting transform.

Appends the given datum transform to this one.

Reverse

public method Reverse → ()

returns → IDatumTransform: The reverse transform.

Returns the reverse datum transform.

Transform

public method Transform → (3)

latitude ⁱⁿ : float64: Latitude in radians, in terms of source horizontal datum.
longitude ⁱⁿ : float64: Longitude in radians, in terms of source horizontal datum.
vertical ⁱⁿ : float64: The vertical coordinate in the source coordinate system.
returns → Vec3D: The resulting longitude (Vec3D.X) and latitude (Vec3D.Y) in terms of target horizontal datums and the vertical coordinate (Vec3D.Z) in the target coordinate system.

Transforms the geographic coordinates from the source datum to the target datum.

Public / Attributes

IsIdentity

[Constant]
public attribute IsIdentity → (get)

value : bool: true if this is the identity datum transform,
false if it is not.

Does this datum transform pass through all input values, without modifying them?

IsVertical

[Constant]
public attribute IsVertical → (get)

value : bool: true if this datum transform modifies only the vertical coordinate,
false if not.

Does this datum transform modify the vertical coordinate only?

If this property returns true, the datum transform modifies the input vertical coordinate and returns the result as the output vertical coordinate, while leaving the input latitude and longitude unchanged. To perform the modification, a datum transform may use the input latitude and longitude, though.
