I am using Mapbox's Geocoding API on iOS (Swift) to reverse geocode coordinates. I have been able to make it work for any land coords, but when on the ocean my code does not run (or print the placemark): 

        let task = geocoder.geocode(options) { (placemarks, attribution, error) in
            guard let placemark = placemarks?.first else { return }

            print(placemark.name)
          }

So is this not supported by the API or is there something I am not seeing, or is there an alternative to this?

I have read their API Documentation and could not find anything...

  • No. How could it? Inspect the response and will find a very low confidence since there are no addresses in the middle of bodies of water – charlietfl Jul 01 '19 at 22:10
  • @charlietfl there is no response. So is there no way to find out if a coordinate is in the Pacific Ocean, for example, using the Mapbox Geocoding? –  Jul 01 '19 at 23:20

No, they do not.

There aren't many API services that reverse geocode in large bodies of water either.

Here is one: https://geocode.xyz/46.195042,-6.767578?geoit=xml (it should work in both land and water. see https://geocode.xyz/api for full api specification)

  • Correct. I emailed the support team and told me that they do not handle queries on oceans that are not administrative entities. –  Jul 03 '19 at 03:26
