Stephanie Joseph LATITUDE AND LONGITUDE Introduction to Coordinate Systems on Earth This exercise is an introduction to a standardized coordinate system used throughout the world for centuries, Latitude and Longitude.

In Google Earth, you can toggle the latitude/longitude grid on/off from the menu bar at the top of the page. Move your cursor to the ‘View’ option on the menu bar and click it. Locate the Lat/Lon Grid option and click it. You will see the latitude/longitude grid appear on the Earth image in Google Earth. Clicking on the Lat/Lon Grid option again will turn off the grid. Alternatively, you can toggle the latitude/longitude grid by simultaneously using the ‘ctrl + L’ keys on your keyboard.

The equator serves as the reference line for latitude and was arbitrarily assigned a value of 0
