find parallels on which the selected object and determine what his latitude.This coordinate determines the angle between the equator and the plumb line at the selected point.Latitude parallels marked on the map and the geographical scope is measured from 0 to 90 degrees.In the southern hemisphere latitudes are called the southern and the northern - north.For example, Cairo (capital of Egypt) is located north of the equator and is located on the parallel of 30 °.Therefore, one of its coordinates - 30 ° north latitude.
Learn to determine the latitude of the object, if it is between the parallels.To do this, determine the latitude parallel
, closest to the selected object, and then add to it the number of degrees meridian arc from the object to this parallel.For example, the Russian capital is located to the north of parallel 50 °.Between her and this parallel - 6 °.It turns out that Moscow is at 56 ° north latitude.
Find meridian on which the selected object and determine its longitude.Longitude - is the angle between the meridian, which is your object, and the initial meridian.Its value may be between 0 and 180 °.Usually longitude marked on the map at the intersection of the equator with the meridians.Longitude, which is east of the zero meridian is called the East, west - west.For example, St. Petersburg is located at 30 ° to the east of the prime meridian, so it coordinates - 30 ° east longitude.
4 Try to determine the longitude of the facility, located between the meridians.In order to determine the longitude of the closest relative to the zero meridian and add the number of degrees of arc parallels between your object and data meridian.For example, the Russian capital is 8 ° east of the meridian of 30 °, then its coordinate - 38 ° east longitude.
