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. The numbers are in decimal degrees format 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.

Coordinate format handling

Different Mapbox services handle coordinate order differently, so check the service's documentation to see how the latitude and longitude should be formatted. For instance, Mapbox GL JS and most Mapbox web services APIs use the format longitude,latitude, while Mapbox.js uses the format longitude,latitude.
