![]() ![]() Latitude coordinates south of the equator and longitude coordinates west of the prime meridian have minus signs when stored in a digital database. The 180 th meridian is the approximate location of the International Date Line.įor the land mass of Canada, latitudes range from about 42 oN to 83 oN and longitudes range from approximately 53° W to 141° W. Longitude is the angular measurement of a location east or west of the prime meridian (which runs through Greenwich, England), ranging from 0° at the prime meridian to 180° E or 180° W. Lines of longitude (also called meridians) run in a north-south direction from pole to pole. ![]() Latitude is the angular measurement of a location expressed in degrees north or south of the equator, ranging from 0° at the equator to 90° N or 90° S at the poles. Lines of latitude (also called parallels) run in an east-west direction around the earth parallel to the equator. ![]() Latitude and longitude coordinates, often referred to as geographic coordinates, are spherical. The coordinate values can be spherical (latitude and longitude) using angular units of measure such as degrees, minutes and seconds or planar (Universal Transverse Mercator) using linear units such as metres.Ĭartographic boundary files, digital boundary files, representative points and road network files are disseminated in latitude/longitude coordinates.Ģ011, 2006, 2001, 1996, 1991, 1986, 1981 (latitude/longitude)ġ996, 1991, 1986, 1981, 1976, 1971 (Universal Transverse Mercator) RemarksĪ coordinate system is usually defined by a datum, ellipsoid and projection, and is specified in terms of units ( e.g., degrees, metres). Detailed definitionĪ coordinate system is a reference system based on mathematical rules for specifying positions (locations) on the surface of the earth.
