Latitude and longitude create a global coordinate system that lets us pinpoint any place on Earth with precision. Latitude measures how far north or south a location is from the equator, while longitude measures how far east or west it is from the Prime Meridian. By turning a place into a pair of numbers, historians and geographers can map where events happened, trace ancient trade routes, compare sites across different times, and analyze spatial relationships—everything from where cities grew to how empires expanded. While longitude has a connection to time zones and latitude to climate patterns, the purpose of these coordinates is to locate places, not to predict climate or determine population density. Population density relies on counting people in a given area, not on the coordinate system itself.
