C# 클래스 SharpMap.CoordinateSystems.CoordinateSystemFactory

Builds up complex objects from simpler objects or values.

ICoordinateSystemFactory allows applications to make coordinate systems that cannot be created by a ICoordinateSystemAuthorityFactory. This factory is very flexible, whereas the authority factory is easier to use.

So ICoordinateSystemAuthorityFactorycan be used to make 'standard' coordinate systems, and CoordinateSystemFactory can be used to make 'special' coordinate systems.

For example, the EPSG authority has codes for USA state plane coordinate systems using the NAD83 datum, but these coordinate systems always use meters. EPSG does not have codes for NAD83 state plane coordinate systems that use feet units. This factory lets an application create such a hybrid coordinate system.

메소드 설명
CreateCompoundCoordinateSystem ( string name, ICoordinateSystem head, ICoordinateSystem tail ) : ICompoundCoordinateSystem

Creates a ICompoundCoordinateSystem [NOT IMPLEMENTED].
CreateEllipsoid ( string name, double semiMajorAxis, double semiMinorAxis, ILinearUnit linearUnit ) : IEllipsoid

Creates an Ellipsoid from radius values.
CreateFittedCoordinateSystem ( string name, ICoordinateSystem baseCoordinateSystem, string toBaseWkt, List arAxes ) : IFittedCoordinateSystem

Creates a IFittedCoordinateSystem.

The units of the axes in the fitted coordinate system will be inferred from the units of the base coordinate system. If the affine map performs a rotation, then any mixed axes must have identical units. For example, a (lat_deg,lon_deg,height_feet) system can be rotated in the (lat,lon) plane, since both affected axes are in degrees. But you should not rotate this coordinate system in any other plane.

CreateFlattenedSphere ( string name, double semiMajorAxis, double inverseFlattening, ILinearUnit linearUnit ) : IEllipsoid

Creates an Ellipsoid from an major radius, and inverse flattening.
CreateFromWkt ( string WKT ) : ICoordinateSystem

Creates a spatial reference object given its Well-known text representation. The output object may be either a IGeographicCoordinateSystem or a IProjectedCoordinateSystem.
CreateFromXml ( string xml ) : ICoordinateSystem

Creates a coordinate system object from an XML string.
CreateGeocentricCoordinateSystem ( string name, IHorizontalDatum datum, ILinearUnit linearUnit, IPrimeMeridian primeMeridian ) : IGeocentricCoordinateSystem

Creates a CreateGeocentricCoordinateSystem from a datum, ILinearUnit">linear unit and

CreateGeographicCoordinateSystem ( string name, IAngularUnit angularUnit, IHorizontalDatum datum, IPrimeMeridian primeMeridian, AxisInfo axis0, AxisInfo axis1 ) : IGeographicCoordinateSystem

Creates a GeographicCoordinateSystem, which could be Lat/Lon or Lon/Lat.
CreateHorizontalDatum ( string name, DatumType datumType, IEllipsoid ellipsoid, Wgs84ConversionInfo toWgs84 ) : IHorizontalDatum

Creates HorizontalDatum from ellipsoid and Bursa-World parameters.

Since this method contains a set of Bursa-Wolf parameters, the created datum will always have a relationship to WGS84. If you wish to create a horizontal datum that has no relationship with WGS84, then you can either specify a DatumType">horizontalDatumType of

CreateLocalCoordinateSystem ( string name, ILocalDatum datum, IUnit unit, List axes ) : ILocalCoordinateSystem

Creates a local coordinate system.

The dimension of the local coordinate system is determined by the size of the axis array. All the axes will have the same units. If you want to make a coordinate system with mixed units, then you can make a compound coordinate system from different local coordinate systems.

CreateLocalDatum ( string name, DatumType datumType ) : ILocalDatum

Creates a ILocalDatum.
CreatePrimeMeridian ( string name, IAngularUnit angularUnit, double longitude ) : IPrimeMeridian

Creates a PrimeMeridian, relative to Greenwich.

Creates a ProjectedCoordinateSystem using a projection object.
CreateProjection ( string name, string wktProjectionClass, List parameters ) : IProjection

Creates a Projection.
CreateVerticalCoordinateSystem ( string name, IVerticalDatum datum, ILinearUnit verticalUnit, AxisInfo axis ) : IVerticalCoordinateSystem

Creates a IVerticalCoordinateSystem from a datum and linear units.
CreateVerticalDatum ( string name, DatumType datumType ) : IVerticalDatum

Creates a IVerticalDatum from an enumerated type value.
