If the user already have a dive site with coordinates that have the same name we can assume that it is the same and pick that one.
If it is a new dive site for the user and there exists multiple sites with the same name, should we show a list for the user to pick from and in that case how much more information about the site should we show other than country.

How big are the deviations between the GPS coordinates??
Should we implement some sort of filter that merges dive site coordinates if they are within 50m 
or whatever error margin the GPS locator has.
