Longitude and Latitude

Note:

• Setting your location, using longitude An imaginary line that extends from the North Pole to the South Pole of Earth. Each line is referred to by the angle between it and the line at 0 degrees longitude (known as the Greenwich Meridian). Each line is therefore known as an angle of longitude. and latitude An imaginary line that extends horizontally around the Earth. Each line is referred to by the angle between it and the line at 0 degrees latitude (known as the Equator). Each line is therefore known as an angle of latitude. coordinates, is important for Designer to accurately set the dawn and dusk times. For more information, see Sunrise and Sunset Considerations.

Lines of Longitude

A line of longitude is an imaginary line that extends from the North Pole to the South Pole of Earth. Each line is referred to by the angle between it and the line at 0 degrees longitude (known as the Greenwich Meridian). Each line is therefore known as an angle of longitude.

Lines of Latitude

A line of latitude is an imaginary line that extends horizontally around the Earth. Each line is referred to by the angle between it and the line at 0 degrees latitude (known as the Equator). Each line is therefore known as an angle of latitude.

Longitude and Latitude can be configured in the properties of the Workgroup (see Workgroup Configuration). This example shows a latitude of 51 degrees, 25 minutes and 0 seconds North of the Equator, and a longitude of 0 degrees, 13 minutes and 0 seconds East of the Greenwich Meridian.

Angles are described in terms of three units: degrees, minutes and seconds. One degree is made up of 60 minutes. One minute is made up of 60 seconds. In an angle, the degrees are denoted by the symbol °; the minutes are denoted by ' and the seconds denoted by ".
