IProjectedCoordinateSystem2.GetGCSParams Method

Returns 180 degrees and horizon delta in proper GCS units.

Public Sub GetGCSParams ( _
    ByRef p_180 As Double, _
    ByRef pDelta As Double _
)

public void GetGCSParams (
    ref double p_180,
    ref double pDelta
);

Description

GetGCSParamscalculates the edge of the horizon for a geographic coordinate system. For example, if your coordinate system is in decimal degrees, 180 is returned. If the units are in grads, 200 is returned. It also returns a delta, a small offset value, in the correct unit of measure.

IProjectedCoordinateSystem2.GetHorizon Method

Returns the standard horizon polygon, its envelope, and whether it is inclusive or exclusive; the horizon polygon may be 0.

Public Function GetHorizon ( _
    ByRef horizonEnvelope As WKSEnvelope, _
    ByRef Inclusive As Boolean _
) As IGeometry

public IGeometry GetHorizon (
    ref WKSEnvelope horizonEnvelope,
    ref bool Inclusive
);

Remarks

GetHorizon returns, in geographic coordinate system coordinates and unit of measure, the valid geometry of a projected coordinate system. The method also returns whether the geometry should be considered inclusive or exclusive, and its envelope.

IProjectedCoordinateSystem2.GetShiftedHorizon Method

Returns the horizon polygon, shifted once or twice, west/east of the standard horizon for a negative/positive shift.

Public Function GetShiftedHorizon ( _
    ByVal shift As Integer _
) As IGeometry

public IGeometry GetShiftedHorizon (
    int shift
);

Remarks

The standard horizon is the valid area of a projected coordinate system, but in geographic coordinate system coordinates and unit of measure. The standard horizon usually has longitude values between +/-180 (or equivalent). If you use -2, -1, 1 or 2 for the shift value, GetShiftedHorizon will translate the horizon by 360 degrees to the left or right.

IProjectedCoordinateSystem2.InverseWithShift Method

Projects points from planar to geographic coordinates. Deals with geographic coordinates in ranges other than +-180.

Public Sub InverseWithShift ( _
    ByVal shift As Double, _
    ByVal Count As Integer, _
    ByRef Points As WKSPoint _
)

public void InverseWithShift (
    double shift,
    int Count,
    ref WKSPoint Points
);

IProjectedCoordinateSystem2.IsEqualNoNames Method

Compares to projected coordinate systems for equality but ignores their names.

Public Function IsEqualNoNames ( _
    ByVal pOther As IProjectedCoordinateSystem _
) As Boolean

public bool IsEqualNoNames (
    IProjectedCoordinateSystem pOther
);

IProjectedCoordinateSystem2.LatitudeOfCenter Property

The latitude of center (Phi C) of a projected coordinate system.

Public Property LatitudeOfCenter As Double

public double LatitudeOfCenter {get; set;}

Remarks

The latitude of center projection parameter is used by the Hotine Oblique Mercator (Azimuth) and Krovak projections. It defines the latitude that is at the center of the projection. It is usually but not always the origin of the Y values.

IProjectedCoordinateSystem2.LatitudeOfOrigin Property

The latitude of the origin (Phi 0) of a projected coordinate system.

Public Property LatitudeOfOrigin As Double

public double LatitudeOfOrigin {get; set;}

IProjectedCoordinateSystem2.LongitudeOfCenter Property

The longitude of center (Lam C) of a projected coordinate system.

Public Property LongitudeOfCenter As Double

public double LongitudeOfCenter {get; set;}

Remarks

The longitude of center projection parameter is used by the Hotine Oblique Mercator (Azimuth) and Krovak projections. It defines the longitude that is at the center of the projection. It is usually but not always the origin of the X values.

IProjectedCoordinateSystem2.PseudoStandardParallel1 Property

The latitude on an oblique spheroid that defines the oblique cone for a Krovak projected coordinate system.

Public Property PseudoStandardParallel1 As Double

public double PseudoStandardParallel1 {get; set;}

IProjectedCoordinateSystem2.PutLinearAndAngularUnits Method

Modify linear unit of projected coordinates and angular unit of associated geographic coordinates.

Public Sub PutLinearAndAngularUnits ( _
    ByVal LinearUnit As ILinearUnit, _
    ByVal AngularUnit As IAngularUnit _
)
