Just geocode the address you receive, then compute the distance between what you provided and what you got back. Decide on a threshold (based on the source of your lat-lng in the first place) for what reverse geocoding you will accept.
Reverse geocoding generally returns the lat-lng of the top of the house. If you are using a lat-lng from, for instance, routing data, the lat-lng you have may be the street in front of the house, which could easily be 100 meters away. Arbitrarily returning "zero results" when the submitted lat-lng is over water wouldn't be a very good design. If your user is "picking" a location from a map, it would be very easy for the user to "miss" the exact top of a sea-side home and click a location a few meters off the beach. - Jeff On Sunday, January 8, 2017 at 4:35:57 PM UTC-8, Xin Zhang wrote: > > Hi, > > > In my project, I'm using Google Geocoding and Reverse Geocoding APIs to > validate the addresses and latlngs provided by end users. > > > Given latlng -37.857866,144.950706, the Reverse Geocoding API ( > https://maps.googleapis.com/maps/api/geocode/json?latlng=-37.857866,144.950706) > > returns the nearest land address. > > However on Google Map web page, that latlng actually is in the sea: > https://www.google.com.au/maps/search/-37.857866,144.950706 > > > Is there anyway that I can tell Google Reverse Geocoding API to not return > me the nearest land address?
