Latitude is angular distance measured north and south of the Equator. The Equator is 0 degrees. As you go north of the equator the Latitude increases all the way up to 90 degrees at the north pole. If you go south of the equator, the Latitude increases all the way up to 90 degrees at the south pole.
On these topographic maps the latitude and longitude units are expressed in degrees, minutes, and seconds. Each degree is subdivided into 60 minutes('). Each minute is divided into 60 seconds(''). Note the similarity to units of time which makes these relationships easy to remember.atitude of the top of the map is 40 30' and the latitude of the bottom of the map is 40 15'. The difference between these two is also 15'. This map, which covers an area that is 15' x 15' would be referred to as a 15 minute map. Notice that latitude and longitude is only fully written in the corners of the map.
