What is the basic grid system utilized for latitude and longitude lines on maps?

The basic grid system utilized for latitude and longitude lines on maps is known as the graticule. This term refers to the network of lines that provide a framework for identifying locations on the Earth's surface. The lines of latitude run parallel to the equator, while the lines of longitude extend from the North Pole to the South Pole. Together, they create a grid that allows every point on Earth to be specified by a set of coordinates, making navigation and mapping possible.

In contrast, the coordinate system is a broader term that encompasses various methods of mapping points in space, not limited to latitude and longitude. The celestial grid pertains specifically to mapping positions of celestial objects, which is distinct from terrestrial mapping. The mapping system is a very general term that can refer to various methods or processes used to create maps, and does not specifically denote the grid used for latitude and longitude. The graticule uniquely captures the defined method for representing the Earth's surface using these specific lines.
