A global grid uses a system of lines of latitude and longitude which allows you to locate any place on Earth with a simple number code and a map grid uses a a system of imaginary to divide up space on a map and you could locate a place that is either in or local to what place the map is representing.

A map grid is a system of intersecting horizontal and vertical lines used to locate points on a map, typically using latitude and longitude coordinates. A global grid, on the other hand, refers to a system of latitude and longitude lines that cover the entire Earth's surface, providing a reference framework for mapping and navigation on a global scale. Essentially, a map grid is a smaller, localized version of the larger global grid.
Area refers to a specific region or area on a map, while grid reference is a system of identifying locations on a map using a grid of horizontal and vertical lines. Grid reference provides a more precise way to pinpoint a location compared to just referring to an area.
An area reference is a general location indicated on a map, such as a city or region, while a grid reference is a specific point identified by intersecting lines on a grid system, such as latitude and longitude coordinates or a military grid reference system (MGRS). Essentially, an area reference gives a broader location, while a grid reference pinpoints a precise position within that area.
The grid on a map helps locate specific points by using a system of coordinates, usually involving letters and numbers. This allows users to pinpoint exact locations, measure distances accurately, and navigate more effectively.
legend that helps users understand the symbols and features on the map. The grid system provides coordinates for location, the scale shows the ratio between distances on the map and actual distances on the ground, and the legend explains the symbols and colors used on the map.
The grid location differs map to map. There are different map projections that particular researchers and cartographers prefer over others, and these different projections alter the grid locations for landmarks.
