**graticule:** A network of parallels and meridians for equal intervals of latitude and longitude on the earth’s surface. The form and appearance of a graticule depends on the map projection employed. The lines comprising a graticule may form a square / rectangular network; a graticule may also be comprised of two families of curves having variable separation between them. The mathematical framework of a map is comprised of a grid, or a graticule, or both. A grid is always comprised of a square network of parallel lines representing particular linear distances on the ground.
