Answer :
You could use coordinates, or depending on what kind of map you might be able to use an address.
On a map, there are lines, going vertically and horizontally around a picture of the globe. These lines are imaginary but they help us calculate absolute location, these lines are called Lattitude and Longitude. My teacher likes to think of Lattitude as "fattitude" like the pants of the globe sides, so that's one way to remember which is which. But if you are looking at a map and need to determine absolute locations, you find where your city is, then look trace a straight line to side of the map with your finger. That is where you find the Lattitude coordinates. Now trace up with yiur finger, this is the longitude coordinates. Hope I helped! :D
