PEI Coordinate SystemProvincial GIS Coordinates
The coordinate plane of the province’s Geographic Information System was realized by using a Double Stereographic Projection with parameters specific to this province as listed below and is referred to as the PEI Survey Reference System.
The projection is referenced to the North American Datum of 1983 realized from the Canadian Spatial Reference System (NAD83(CSRS)).
The Geodetic Reference System of 1980 (GRS80) is the ellipsoid upon which the datum is realized. This reference ellipsoid or ellipse of revolution, was fixed in 1980 as a "best" means to mathematically represent the earth’s surface.
Parameters for the PEI Survey Reference System are as follows:
|Projection||Stereographic Double Projection|
|Origin||Latitude: N 47° 15'
Longitude: W 63° 00'
|Scale Factor at Origin||0.999912|
|False Origin||Northing: 800,000 Metres
Easting: 400,000 Metres
|First Eccentricity e² =0.006694380|
|Second Eccentricity e'² =0.006739497|
|Gaussian Mean Radius at Origin =6,379,782.0995 Metres|
PEIGeocalc is a transformation software that enables coordinates to be converted to and from various projections and datums such as NAD83(CSRS), ATS77, or again NAD27. For further information or to obtain a copy of this software contact:
