Grid

• Grids help you locate places on maps.

• A grid uses lines to make rows and columns on a map.

• The rows go from side to side. • The columns go up and down.

Sometimes a grid uses a number and letter system to locate a specific place on a map

The blue house is located at what location?

What is located in C4?

The hot air balloon is flying over what area?

But most of the time we use latitude and longitude coordinates.

Lines of Latitude

• These are imaginary lines that measure distance north or south of the equator and run from east to west on the map.

• These lines are also called parallels because they do not touch.

Lines of Longitude

• These are imaginary lines that measure distance east or west of the prime meridian and run from north to south on the map.

• These lines connect at the north and south poles. These lines are also called meridians.

Compass Rose• The compass rose shows you

directions on a map• Cardinal directions are north,

south, east, and west• Intermediate directions are

northeast, northwest, southwest, and southeast

Legend/Key

• A legend or key lists and explains the symbols and use of color on the map

Scale• The scale on a map helps us estimate

the distance between places. • Scale is the relationship between

distance on the map and distance on the ground.

• For example, a 1:24,000 scale map means that for every 1 inch on the map, it represents 24,000 inches on the ground.
