I'm working on a GeoTargeting application. I'm curious if longitude and latitude of a point on the earth can change?
If you know the exact position of the statue of liberty how sure is it that longitude and latitude will stay the same.
Does it change according to the season, time in the year, or slowly over time
As you move away from the Equator every degree latitude is a little smaller as you are no longer measuring the Earth circumference at the Earth's widest point. The North Pole is 90 degrees north latitude and is actually just a point.
Typically, this center is the location's unique latitude and longitude degrees. Yet, while no one city in the world can have the same latitude and longitude, many cities share one or the other, even if they're on the opposite ends of a country.
Longitude increases as you leave the Prime Meridian (0 degrees) going east (0 to 180 degrees) and decreases as you head west (0 to -180 degrees), until they meet at 180 degrees.
Wikipedia to the rescue:
The surface layer of the Earth, the lithosphere, is broken up into several tectonic plates. Each plate moves in a different direction, at speeds of about 50 to 100 mm per year. As a result, for example, the longitudinal difference between a point on the equator in Uganda (on the African Plate) and a point on the equator in Ecuador (on the South American Plate) is increasing by about 0.0014 arcseconds per year.
