![]() ![]() For example, 11 U 705863 m E 5658841 m N are the approximate coordinates for the Calgary Tower. The easting is always given first, followed by the northing. ![]() Figure T11: Universal Transverse Mercator (UTM) zones 11 U and 12 U in Alberta.Ī UTM coordinate always begins with the zone, which in the case for most of Calgary is 11 U. Zones are designated by a number and a letter, e.g., the city of Vancouver, BC is in UTM zone 10 U. Figure T10: Universal Transverse Mercator (UTM) zones in Canada. The city of Calgary is actually divided into two UTM zones: zone 11 U and zone 12 U (Figure T11). Inside each zone, coordinates are measured in metres north and east. In this grid system designed by the military, Earth’s surface is divided into 60 north-south zones designated by a number and letter, each covering 6° of longitude in width (Figure T10). What geographic feature is located at 51☀2’39” N 114☀3’47” W? See Appendix 2 for Google Earth Tutorial answers. Try typing these coordinates into the search bar in Google Earth. Together, these coordinates describe an exact location. Notice that latitude is listed first, followed by longitude. For anywhere in Canada, latitude will always be north of the equator and longitude will always be west of the prime meridian, e.g., 51☀2’39” N 114☀3’47” W. When using the geographic grid system, one must specify whether coordinates are north (N) or south (S) of the equator, and east (E) or west (W) of the prime meridian. ![]() The line of 0° latitude is the equator, and latitude increases from 0° to 90° as you move north or south towards the poles. The line of 0° longitude is the prime meridianlocated in Greenwich, England, and longitude increases from 0° to 180° as you move east or west away from the prime meridian. Depending on the accuracy required in locating a point on a map, degrees (°) may be subdivided into 60 subdivisions known as minutes (‘) and minutes may be subdivided into 60 subdivisions known as seconds(“). Figure T9: Geographic grid system displayed over southern Alberta.Ĭoordinates that describe an exact location on the surface of Earth are represented in degrees, minutes and seconds of latitude and longitude. Meridians of longitude run north-south whereas parallels of latitude run east-west. Figure T8: The geographic grid system is comprised of meridians of longitude and parallels of latitude. ![]() Figures T8 and T9 illustrate the geographic grid system in Canada. The geographic grid system is made up of meridians of longitude and parallels of latitude. If you are not sure which grid system you are using, return to the Options menu to check.
