Projection Property

Type

GeoCalcNET.Projection

Access

Get/Set

Description

The Projection property provides access to the Projection used in this ProjectedCoordSys.  

Example

[VB]

Private Sub GeoCalcNET_ProjectedCoordSys_Projection(ByVal cs As GeoCalcNET.ProjectedCoordSys, ByVal data As GeoCalcNET.DataSourceComponent)

Dim p As GeoCalcNET.Projection = cs.Projection

cs.Projection = New GeoCalcNET.Projection(GeoCalcNET.Projection.ClassType.TransverseMercator, cs.Datum)

If cs.Projection.Parameters.Exists("central_meridian") Then

Dim av As New GeoCalcNET.AngularValue

av.InDegrees = 147

cs.Projection.Parameters.AngularItem("central_meridian") = av

End If

If cs.Projection.Parameters.Exists("latitude_of_origin") Then

Dim av As New GeoCalcNET.AngularValue

av.InDegrees = 0

cs.Projection.Parameters.AngularItem("latitude_of_origin") = av

End If

If cs.Projection.Parameters.Exists("false_easting") Then

Dim lv As New GeoCalcNET.LinearValue

lv.InMeters = 500000

cs.Projection.Parameters.LinearItem("false_easting") = lv

End If

If cs.Projection.Parameters.Exists("false_northing") Then

Dim lv As New GeoCalcNET.LinearValue

lv.InMeters = 0

cs.Projection.Parameters.LinearItem("false_northing") = lv

End If

End Sub

[C#]
