Respuesta :
Our earthly grid system is also referred to as a graticule and consists of lines of latitude and longitude.
What is graticule ?
The graphic depiction of a coordinate system as a grid of lines on a map is called a graticule, and each line on the grid represents a fixed coordinate value. As a result, it can be considered a form of isoline and is widely depicted on maps of all kinds, at scales ranging from the local to the global.
The phrase is almost always used to expressly refer to the parallels and meridian of latitude and longitude, respectively, in the geographic coordinate system. Grid lines for other coordinate reference systems, such as Universal Transverse Mercator, are regularly shown on maps for the same reasons, with a similar meaning, and with a similar shape, but they are rarely referred to as graticules.
