    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.
