A map or a grid
You find the lines of latitude and longitude and find the place that they intersect, which is your location.
Every point on Earth has both a longitude and a latitude. And if someone gives you a longitude and a latitude, you can use them to find exactly one point on Earth.
they use it to find enemy bases
GPS
You find latitude by finding the place on the map and see what line it is between or on. The same with longitude. You can also find the latitude and longitude of an address using Google maps.
Use the latitude and longitude lines on the map along with the coordinates. Find where the two coordinates meet and that will be the location you are looking for.
The equator is the zero reference line for latitude, and the Prime Meridian is the one for longitude.

~ to find latitude and longitude (best answer)~also where a place is
You would use coordinates, such as latitude and longitude, to find the absolute location of a place on a map. These coordinates provide a precise and fixed point on the Earth's surface.
GPS receivers do not 'use' elevation for anything. They use the signals from several satellites simultaneously to calculate the latitude, longitude, and elevation of the receiver's location. It takes a minimum of three satellites to calculate the latitude and longitude, a minimum of four satellites to calculate the latitude, longitude, and elevation, if more satellites can be found the latitude, longitude, and elevation calculations can be refined more accurately.
