Method Create

Create(Int32)

Returns an instance of the SpatialReference class based on the given well-known ID.

Declaration

public static SpatialReference Create(int wkid)

Parameters

Type	Name	Description
System.Int32	wkid	The well-known ID of the horizontal coordinate system. Must be a positive value.

Returns

Type	Description
SpatialReference	A SpatialReference object.

Remarks

The returned SpatialReference has only horizontal coordinate system and does not have vertical coordinate system associated with it.

Relevant samples

Densify and generalize: A multipart geometry can be densified by adding interpolated points at regular intervals. Generalizing multipart geometry simplifies it while preserving its general shape. Densifying a multipart geometry adds more vertices at regular intervals.

Identify layers: Identify features in all layers in a map. MapView supports identifying features across multiple layers. Because some layer types have sublayers, the sample recursively counts results for sublayers within each layer.

Create(Int32, Int32)

Returns an instance of the SpatialReference class based on well-known IDs for the horizontal and vertical coordinate systems.

Declaration

public static SpatialReference Create(int wkid, int verticalWkid)

Parameters

Type	Name	Description
System.Int32	wkid	Well-known ID (WKID) of the horizontal coordinate system. Must be a positive value.
System.Int32	verticalWkid	Well-known ID (WKID) of the vertical coordinate system. Must be a non negative value.

Returns

Type	Description
SpatialReference	A SpatialReference object.

Remarks

The method returns a spatial reference that has both horizontal and vertical coordinate systems. When verticalWkid is 0, this method is equivalent to calling Create(Int32), and does not define a vertical coordinate system part.

Create(String)

Returns an instance of the SpatialReference class based on well-known text (WKT).

Declaration

Parameters

Type	Name	Description
System.String	wktext	A well-known text (WKT) string that defines a horizontal and optionally vertical coordinate system.
