Summary
An overview of how the Earth's grid system of latitude and longitude is used to precisely pinpoint any location on the globe.
Highlights
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.
