A geographical grid is a system of intersecting lines used to locate points on a map or plot coordinates on the Earth's surface. It typically consists of lines of latitude and longitude that create a network of squares or rectangles to aid in navigation and cartography. This grid system helps to accurately pinpoint locations and measure distances on a map or globe.
