Take care not to confuse the latitude and longitude lines with UTM lines, another type of grid coordinate system often found on maps.The map should also indicate where the latitude and longitude depicted are relative to the equator and prime meridian, respectively (e.g., North or South, East or West).For instance, there may be a Graticule marked at every minute within a degree instead of every degree (e.g., 32☀′, 32☁′, and so on). Depending on the scale of your map, the graticules may mark fractions of degrees rather than whole degrees.Longitude graticules are marked on the north and south edges. Latitude graticules are marked along the east and west edges of the map.These numbers are called “graticules.” X Research source Look for numbers along the edges of the map giving coordinates for each line.

Latitude is indicated on a map by a series of evenly-spaced horizontal lines running from one side of the map to the other, while longitude is indicated by a series of evenly-spaced vertical lines running from top to bottom. Locate the latitude and longitude markers.
