latitude and longitude
Latitude and longitude are a pair of numbers (coordinates) used to describe a position on the plane of a geographic coordinate system. Across the Mapbox product ecosystem, latitude and longitude are formatted in decimal degrees and range from -90 to 90 for latitude and -180 to 180 for longitude.
For example, Washington DC has a latitude 38.8951 and longitude -77.0364. In API calls you will often see the numbers placed together and separated by a comma: -77.0364,38.8951. In some cases, altitude can be included as a third value.
Find a location's coordinates
If you want to find a location's coordinates, use the Location Helper which allows you to search for a location and copy its coordinates for use in your code.
Present coordinates in real time
The Get coordinates of the mouse pointer Mapbox GL JS example shows how to query the geographic coordinates for the position of the mouse cursor on a web map.
Adding longitude and latitude lines to your map
If you want to add visible longitude and latitude lines (a graticule) to your map, there are community plugins for Mapbox GL JS available, or you can add a graticule dataset to your map style. A list of graticule datasets is located at geojson.xyz.
Coordinate format handling
Different Mapbox services handle coordinate order differently. When you start using a Mapbox product, read its documentation to see how the latitude and longitude should be formatted. For example, Mapbox GL JS and most Mapbox web services APIs use the format longitude,latitude, while other products including the Mapbox Maps SDK for iOS use the format latitude,longitude.
