Write a paragraph describing a real-world application in which the coordinate grid system is used. Include a simple example specific to your application and a diagram, if appropriate. You can use an idea from the movie or search the Internet. If you do get your idea from the movie or the Internet, please cite your source.

One real-world application in which the coordinate grid system is used is for navigation and mapping. GPS (Global Positioning System) devices extensively employ the coordinate grid system to determine and display the location of an individual or object on Earth's surface. For example, when using a GPS to find the nearest gas station, the device uses latitude and longitude coordinates to pinpoint the user's location and calculate the shortest route to the desired destination. The coordinate grid system allows for precise positioning and accurate mapping, making it an indispensable tool for navigation in various fields such as aviation, transportation, and outdoor activities.
