For longitude, you can use the letter E or a positive number for the eastern direction, and the western direction can be indicated by the letter W, or a negative number. For latitude, northern directions may be indicated by the letter N or a positive number, and southern directions can be marked with either the letter S or a negative value. To specify the cardinal direction, you can use letters or positive and negative numbers.

Now that you know what is latitude and longitude, let's see how to write coordinates in GPS, our lat long converter, or any other tool. Find out how in the latitude longitude distance calculator and the azimuth calculator! All meridians have the same length - 12,429.9 miles (20,003.93 km).ĭid you know that you can calculate the shortest possible distance between two points of known geographical coordinates using latitude and longitude? You can also estimate the direction you need to point your compass to get from one point to the other. They extend to the east and west of the Prime Meridian, reaching up to 180 degrees. Lines of longitude, or meridians connect the North and the South Pole. Longitude, on the other hand, refers to a east-west position on the Earth. The maximum value of latitude is 90 degrees - found at the poles. The central line of latitude is called the Equator. It's represented by circles of latitude, or parallels - the lines that go around the globe. It references the north-south position on the Earth. Latitude is the angle between the equatorial plane and the line extending from the center of the Earth to a certain point on its surface. We specify coordinates using latitude and longitude. It originates from the intersection of the Prime Meridian (Greenwich, England) with the Equator. The geographical coordinate system is based on the spherical coordinate system for an ellipsoid - the shape of the Earth.

Start Coordinate Converter available in OnPOZ Tools (found in Windows Main Menu under Effigis ).With coordinates, you can locate any place on the Earth to a high degree of accuracy. If no site displacement is applied after datum conversion, as it is performed in most converters, then, strictly speaking, the resulting coordinates are in NAD83 with a reference epoch of today. Whereas in most converters, the output coordinate is at the same epoch as the input’s, in Coordinate Converter it is also possible to apply a temporal effect that will make a coordinate change through time due to the Earth’s crust motion.įor example, the rigorous conversion of a WGS84 coordinate (collected with a GPS receiver, today) to NAD83 (reference epoch: 2010) requires to add the temporal displacement of the point on top of the normal 7 parameters conversion.
A special feature of this converter allows taking into consideration the site velocity to translate the coordinates domain in time. All datums supported by EZSurv are also supported by Coordinate Converter. Coordinate Converter is a simple tool used to convert coordinates between different datums.
