Constructor SpatialReference
SpatialReference(Int32)
Initializes a new instance of the SpatialReference class.
Declaration
public SpatialReference(int wkid)Parameters
| Type | Name | Description |
|---|---|---|
| System.Int32 | wkid | The well-known ID that represents the Spatial Reference. |
Remarks
Each spatial reference can be represented by either a well-known ID (wkid), or a well-known text (wkt). Spatial References define the spatial properties of a geometry, for instance the coordinate system it uses. There are 2 broad classes of coordinate systems - Geographic & Projected. A Geographic Coordinate system uses a 3-dimensional spherical surface to define locations on the earth. A Projected Coordinate system on the other hand uses a flat, 2-dimensional surface. More information about spatial references and coordinate systems is available here.
It is very important to associate spatial data, such as geometry objects, with corresponding spatial references.
