I was looking with my own eyes and didnt see the lights from any ships, so I didnt understand at first why this party of ships was supposedly happening at 0N/0E. The GPS position on a smartphone is accurate to within about 5 meters (16 feet), but processed CORS data can provide longitude accurate to within a few centimeters, along with latitude and height positions. Coordinates help engineers plan the best spot for a building, bridge, well, or other structure. [5][6][verification needed]. Although latitude lines are always equally spaced, longitude lines are furthest from each other at the equator and meet at the poles. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. Or its just the site of a weather observation buoy.

The Prime Meridian separates the Eastern and Western Hemispheres. As you pass the International Date Line, you either add a day (going west) or subtract a day (going east.)Hemispheres. However you see it, we have the GIS world to thank for putting Null Island on the mapin its own, strange way. But for most standard geocoding, chances are, if youve ever geocoded less-than-perfect data and didnt check your results, some of your data points have probably visited this one peculiar spot in the Gulf of Guinea. The prime meridian is an imaginary line dividing the earth into East and West Hemispheres, at 0 longitude. Misspelled street names, non-existent building numbers, and other quirks can create invalid addresses that can confuse a geocoder so that the output becomes 0,0. These start at the Greenwich meridian line and are labeled from 0 to 90 degrees east. Most of Earth's landmasses, including all of Asia and Australia, and most of Africa, are part of the Eastern Hemisphere.The Western Hemisphere is west of the prime meridian and east of the International Date Line.

To be exact, the intersection of zero degrees latitude and zero degrees longitude falls about 380 miles south of Ghana and 670 miles west of Gabon. In a geographical coordinate system, the prime meridian is described as a line of longitude at which the coordinate of longitude is zerodegrees (0). The distance around Earth measures 360 degrees. The Earth is tilted 23.5 degrees from the plane of the Earth's revolution around the sun each year. A section has been cut away to show longitude lines (or meridians) that run vertically around the Earth. In terms of computing and placename databases, the coordinates for Null Island were added to the Natural Earth public domain map dataset[7][8][9] c.20102011, after which the term came into wide use (although there is evidence of it being used previously). Because of Earth's curvature, the actual distance of a degrees, minutes, and seconds of longitude depends on its distance from the Equator. Rosenberg, Matt.

In creating a . Unfortunately, due to human typos, messy data, or even glitches in the geocoder itself, the geocoding process doesnt always run so smoothly. The greater the distance, the shorter the length between meridians. She or he will best know the preferred format. All the meridians on Earth are great circles. While the equator divides Earth into Northern and Southern Hemispheres, it is the prime meridian at zero degrees longitude and the line of longitude opposite the prime meridian (near the International Date Line) at 180 degrees longitude that divides Earth into the Eastern and Western hemispheres., The Eastern Hemisphere consists of Europe, Africa, Asia, and Australia, while the Western Hemisphere includes North and South America.

Where should I start working out out of shape? As the base line for parallels, the equator is considered to be 0 degrees latitude. It finally dawned on us that anytime someone in Los Angeles or Hong Kong or Dubai or anywhere else in the world first turned on their AIS system, before it obtained its first GPS fix, it defaulted to reporting its position as 00-00N / 00-00E and showed up on our AIS display in the Gulf of Guinea.
