GeographicSpatialReferenceSystem Class

A Geographic SRS is an SRS that is based on longitude and latitude. A Geographic SRS can be two dimensional or three dimensional. If geographic SRS is three dimensional, then it is actually a compound SRS of two dimensional SRS and vertical SRS.

The GeographicSpatialReferenceSystem type exposes the following members.

Properties

	Name	Description
	AngularUnit	Unit, used for angular dimensions, in this SRS.
	AsCompound	Returns this SRS converted to CompoundSpatialReferenceSystem. Use IsCompound to find out if conversion is possible. (Inherited from SpatialReferenceSystem.)
	AsGeocentric	Returns this SRS converted to GeocentricSpatialReferenceSystem. Use Type to find out if conversion is possible. (Inherited from SpatialReferenceSystem.)
	AsGeographic	Returns this. (Overrides SpatialReferenceSystemAsGeographic.)
	AsLocal	Returns this SRS converted to LocalSpatialReferenceSystem. Use Type to find out if conversion is possible. (Inherited from SpatialReferenceSystem.)
	AsProjected	Returns this SRS converted to ProjectedSpatialReferenceSystem. Use Type to find out if conversion is possible. (Inherited from SpatialReferenceSystem.)
	AsVertical	Returns this SRS converted to VerticalSpatialReferenceSystem. Use Type to find out if conversion is possible. (Inherited from SpatialReferenceSystem.)
	AxisesOrder	Order of axises in this SRS. If this SRS is not valid and has wrong axises directions, Invalid is returned.
	DimensionsCount	Returns dimensions count in this SRS. For geographic SRS this can be: two - if this is single geographic SRS. three - if this is compound SRS, which consists of single, two dimensional, geographic SRS and vertical SRS, that adds third dimension. (Overrides SpatialReferenceSystemDimensionsCount.)
	EpsgCode	If this objects identifier is EPSG identifier - return its code. Otherwise - return -1. (Inherited from IdentifiableObject.)
	GeographicDatum	Returns geographic datum of this SRS. (Inherited from SpatialReferenceSystem.)
	HasGeographicDatum	Returns , since geographic SRS always have prime meridian. (Overrides SpatialReferenceSystemHasGeographicDatum.)
	HasPrimeMeridian	Returns , since geographic SRS always have prime meridian. (Overrides SpatialReferenceSystemHasPrimeMeridian.)
	Identifier	Identifier of this identifiable object. (Inherited from IdentifiableObject.)
	IsCompound	Returns whether this SRS is compound (a union of two SRS). Following combinations of SRS in compound SRS are considered valid: Geographic SRS + Vertical SRS, in this case type of compound SRS will be Geographic. Projected SRS + Vertical SRS, in this case type of compound SRS will be Projected. If combination of SRSs differs, type of compound SRS will be Unknown. (Inherited from SpatialReferenceSystem.)
	IsSingle	Returns whether this SRS is single (not a union of two SRS). (Inherited from SpatialReferenceSystem.)
	IsValid	Same as Validate(String), but don't return error message. (Inherited from SpatialReferenceSystem.)
	Name	Name of this object. (Inherited from IdentifiableObject.)
	PrimeMeridian	Returns prime meridian of this SRS. (Inherited from SpatialReferenceSystem.)
	Type	Returns Geographic. (Overrides SpatialReferenceSystemType.)

Methods

	Name	Description
	CreateTransformationTo	Creates transformation from this SpatialReferenceSystem to another SpatialReferenceSystem. (Inherited from SpatialReferenceSystem.)
	Equals	(Inherited from Object.)
	ExportToWkt	Returns representation of this SRS as WKT string. The result WKT string will match OGC 01-009 specification, usually named "WKT1". (Inherited from SpatialReferenceSystem.)
	Finalize	(Inherited from Object.)
	GetAxis	Get Axis that describes dimension. (Inherited from SpatialReferenceSystem.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	GetUnit	Get Unit of dimension. (Inherited from SpatialReferenceSystem.)
	IsEquivalent(SpatialReferenceSystem)	Detects whether this SRS is equivalent to other SRS. . (Inherited from SpatialReferenceSystem.)
	MemberwiseClone	(Inherited from Object.)
	ToString	(Inherited from Object.)
	TryCreateTransformationTo	Creates transformation from this SpatialReferenceSystem to another SpatialReferenceSystem. (Inherited from SpatialReferenceSystem.)
	Validate	Determine if this SRS is valid. (Inherited from SpatialReferenceSystem.)
