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.
Reading Latitude and Longitude on a map If you look at the picture above you will notice the latitude and longitude in the upper right hand corner of the map. You would read it as 35 degrees 22 minutes 30 seconds north latitude and 111 degrees 30 minutes west longitude. Below the title you will notice the words 7.5 minute map. This means that the map covers an area of 7.5 minutes of latitude and longitude. Lets look at how we can determine location in terms of latitude and longitude from a topographic map. The diagram below is a very simplified version of a topographic map.
