you can filter results of reverse geocoding result type , location type. in result type can natural_feature , location type should geometric_center or approximate exclude rooftop address can close given point on land.

please have @ following request:

https://maps.googleapis.com/maps/api/geocode/json?latlng=40%2c-74&result_type=natural_feature&location_type=geometric_center%7capproximate&key=your_api_key

the first 2 items in response are:

• north atlantic ocean (type: natural_feature, place id: chijeq3jdsmo3qorbgvpwfckzuq)
• atlantic ocean (type: natural_feature, place id: chij_7hu48qbwgyrt1mq81cinky)

https://maps.googleapis.com/maps/api/geocode/json?latlng=40.044043%2c-74.124069&result_type=natural_feature&location_type=geometric_center%7capproximate&key=your_api_key

the first result 'drum point rd, brick, nj 08723, usa' of type route.
