![]() The image above only displays the 15°, 30° and 45° lines of latitude below the Equator. There will be lines of latitude representing 1°, 2°, 3°, and so on up to 90°. Moving south of the Equator, each line of latitude increases by 1° as well. Therefore, we have 15°N, 30°N, 45°N, and so on. You will notice that the 90° line of latitude is represented by a dot at the North Pole.Īll lines of latitude above the Equator are indicated with the letter ‘N’ to denote north of the Equator. The image above only displays the 15°, 30°, 45°, 60°, 75° and 90° lines of latitude above the Equator. Therefore, there will be lines of latitude representing 1°, 2°, 3°, and so on up to 90°. Moving north of the Equator, each line of latitude increases by 1°. ![]() The Equator is represented as 0° latitude. The longest and main line of latitude is called the Equator. Lines of latitude are horizontal lines that stretch from east to west across the globe. The image shows the lines of latitude and longitude. Using both sets of lines provides a coordinate for the different places around the world. Reading and understanding GPS coordinates requires a basic understanding of navigation using the lines of latitude and longitude. ![]() The GPS system makes use of the geographical lines of latitude and longitude to provide coordinates for a person’s location or a place of interest. Originally a system used only by the military, the GPS system became available for use by citizens almost 30 years ago. Using low-powered radio waves, devices can communicate with the satellites to accurately determine one’s location on the globe. This is made possible by the network of 24 man-made satellites, called GPS satellites, which orbit above the Earth at great speeds and precision. It is commonly used for pinpointing one’s exact location anywhere on the Earth’s surface and obtaining the current time at a specific location. GPS stands for Global Positioning System a system used for worldwide navigation and surveying. Once you understand that, reading coordinates is very easy, and you can practice with online tools. Before we dive into the reading of GPS coordinates, it is important that you have a good grasp of the GPS system and basic knowledge of the geographical lines of latitude and longitude.
