LRIS 1985 Basemap 1:1000 (Summerside)

Frequently-anticipated questions:

What does this data set describe?

    Title: Prince Edward Island 1:1,000 Base Mapping Canada
    This large scale mapping was produced from aerial photography in April, 1985.
    ***** Spatial Reference Information (Beg) *****

    Projection Parameters The coordinate plane of the province%u2019s 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%u2019s 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


    NAD 83(CSRS) Datum Parameters a=6378137.0000 b=6356752.3141 1/f=298.257222101 First Eccentricity e =0.006694380 Second Eccentricity e' =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: Chief Surveyor: Serge Bernard
