Understanding Latitude and Longitude

Introduction to Earth's Grid System00:00:04

The Earth is mapped using an invisible grid of latitude and longitude lines, which allows for the precise location of any point on the planet.

Understanding Latitude00:00:44

Lines of latitude, or parallels, run east-to-west and are equidistant. They are measured in degrees, minutes, and seconds, starting from the 0-degree equator and including significant markers like the Tropics and the Arctic/Antarctic Circles.

Understanding Longitude00:01:55

Meridians of longitude run north-to-south and converge at the poles. The Prime Meridian at 0 degrees, passing through Greenwich, England, serves as the starting point for these measurements.

Pinpointing Locations00:02:25

By combining latitude and longitude coordinates, specific locations such as the Coronado Bridge in San Diego can be identified with high precision.
