Blueprint Project Summary of videos Using coordinate grids is the most useful way to map information, they are used in archaeology, space and navigation. On maps coordinate grids are used for navigation to track time zones and distance. For archaeology coordinate grids are used to record the location of artifacts and structures. In space they use a latitude and longitude maps, thanks to coordinate grids they are able to use this. So, coordinate grids are especially important because without it we wouldn’t be able to use many things today. Real-world application of the coordinate plane The best real-world application example in which the coordinate grid system is used would be a GPS. Lattitude and longitude is also the same thing. Even here in the U.S we basically use the coordinate grid system for everything in every city because we are set up that way. The lines would represent a street and every block would maybe be the buildings in them.
