Answer:
The correct answer is - Grid system.
Step-by-step explanation:
The grid system on the maps is the element that can be used for determining the relative location of a place. The grid system is actually composed of lines, horizontal and vertical ones, representing the longitudinal and latitudinal lines. Each line has its own number, a number that gives us the information about the lines distance from the Equator (the horizontal ones) or from the Prime Meridian (the vertical ones), and if the user knows how to measure the distance by using that information that he/she can easily determine the coordinates of a place.
