Configuration

Config

The configurator object for this type.

public static property Config { get }
type IConfigurator<Ellipsoid>
value [not-null] The configurator object.

ToConfig

Returns the configuration value that describes this object.

public override method ToConfig ()
type ConfigValue
returns [not-null] The configuration value.
overrides GeoObject.ToConfig

Remarks:

All configurable objects need to implement this interface. For simple types, it is preferable to delegate to ToValue.

The returned value may be of type Invalid, which means that this object in its current state cannot be described with the configuration API.

Before returning the resulting configuration value, Cache must be called on it, passing this IConfigurable object as parameter.

Public / Constructors

Ellipsoid

Creates a new instance of Ellipsoid.

public constructor Ellipsoid (float64 semiMajorAxis, float64 semiMinorAxis = 0, float64 inverseFlattening = 0, UnitOfMeasure unit = null, string name = null)
params semiMajorAxis [>0] The semi major axis (a).
  semiMinorAxis The semi minor axis (b) or 0. Defaults to 0.
  inverseFlattening The inverse flattening (1/f) or 0. Defaults to 0.
  unit The unit of measure to use. If null, Metre will be used. Defaults to null.
  name Human-readable name of the geo object. If empty or null, UserDefined will be used instead. Defaults to null.

Public / Methods

Deserialize

Initializes the state of this object from the given data stream.

public override method Deserialize (int32 serialVersion, ISerializer data)
type ISerializable
params serialVersion [>=1] The serial data version.
  data [not-null] The serial data stream.
returns [not-null] The deserialized object. This will typically be this, but in some circumstances, another instance may be returned (e.g. singletons).
overrides GeoObject.Deserialize

Remarks:

The Deserialize method will be called immediately after the object has been instantiated via its default constructor.

The provided serialVersion number is guaranteed to be equal to or less than the SerialVersion returned by this object (i.e. ISerializable object must provide backwards compatibility).

See also:

ISerializable.Serialize
ISerializable.SerialVersion

Equals

Compares this object with the given one.

[Pure]
public override method Equals (IGeoObject other)
type bool
params other The object to compare to.
returns true if this object is equal to other, false if not.
overrides GeoObject.Equals

Compares this object with the given one.

[Pure]
public override sealed method Equals (object other)
type bool
params other The object to compare to.
returns true if this object is equal to other, false if not.
inherited GeoObject.Equals

GetHashCode

[Pure]
public override sealed method GetHashCode ()
type int32
inherited GeoObject.GetHashCode

RadiusOfConformalSphere

Radius of conformal sphere: RC

[Pure]
public method RadiusOfConformalSphere (float64 phi)
type float64
params phi The latitude angle, in radians.
returns Radius of conformal sphere.

Remarks:

This is a function of latitude and therefore not constant. When used for spherical projections the use of Latitude (or Parallel1 as relevant to method) for phi is suggested, except if the projection is equal area when RadiusOfAuthalicSphere should be used.

RadiusOfCurvatureInTheMeridian

Radius of curvature in the meridian: rho

[Pure]
public method RadiusOfCurvatureInTheMeridian (float64 phi)
type float64
params phi The latitude angle, in radians.
returns Radius of curvature in the meridian.

Remarks:

Radius of curvature of the ellipsoid in the plane of the meridian at latitude phi.

RadiusOfCurvatureInThePrimeVertical

Radius of curvature in the prime vertical: nu.

[Pure]
public method RadiusOfCurvatureInThePrimeVertical (float64 phi)
type float64
params phi The latitude angle, in radians.
returns Radius of curvature in the prime vertical.

Remarks:

Radius of curvature of the ellipsoid perpendicular to the meridian at latitude phi.

Serialize

Serializes the current state of this object to the given data stream.

public override method Serialize (ISerializer data)
params data [not-null] The serial data stream.
overrides GeoObject.Serialize

See also:

ISerializable.Deserialize
ISerializable.SerialVersion

ToString

[Pure]
public override sealed method ToString ()
type string
inherited GeoObject.ToString

ToUnit

Converts the length unit of this ellipsoid.

[Pure]
public method ToUnit (UnitOfMeasure unit)
type Ellipsoid
params unit [not-null] The length unit to convert to.
returns [not-null] The resulting ellipsoid.
