State of Oregon
State Plane Coordinate System of 1983
Projection for Oregon North Zone
The State Plane Coordinate System (SPCS) divides the United States into a number of zones, and defines a different projection for each zone such that a suitable map of any given zone is plotted. SPCS is used mainly for intrastate views such as county or parish maps.
Unlike most forms of projection where the datum may be specified separately, the SPCS is tied to a specific datum. There are two State Plane Coordinate Systems commonly used. The State Plane Coordinate System of 1927 uses the North American Datum of 1927 (NAD27), while the State Plane Coordinate System of 1983 uses the North American Datum of 1983 (NAD83).
