SpatialReference Class
Defines the spatial reference of a view, layer, or method parameters. This indicates the projected or geographic
coordinate system used to locate geographic features in the map. Each projected and geographic coordinate system is
defined by either a well-known ID (WKID) or a definition string (WKT). Note that for versions prior to ArcGIS 10,
only WKID was supported. For a full list of supported spatial reference IDs and their corresponding definition
strings, see Using spatial references.
