how to know whether a point is on land or water using google maps api

Question

I want to know whether a point is on land or water using google maps geocoding api.

If I give my coordinate point as (40,-74) which is on water body, I am still getting address which is shown below.

the address is:1416 Highland Ave, Cinnaminson, NJ 08077, USA results[0].geometry.locationType:ROOFTOP results[0].types[0].toString():street_address(which has to be "natural_feature")

I am using java client library to do this. Anyone help me because I have strucked up here and has to submit my assignment where soon. Thanks in Advance.

Answer 1

您可以按结果类型和位置类型过滤反向地理编码的结果。在结果类型中，您可以查找natural_feature，并且位置类型应该是GEOMETRIC_CENTER或APPROXIMATE，以排除任何可以接近陆地上给定点的ROOFTOP地址。

请查看以下请求：

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

回应的前两项是：

• 北大西洋（类型：natural_feature，地点ID：ChIJeQ3JDsMo3QoRBGVpwFckZUQ）
• 大西洋（类型：natural_feature，地点ID：ChIJ_7hu48qBWgYRT1MQ81ciNKY）

现在，如果我对陆地上的点执行相同的请求：

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

第一个结果将是＆＃39; Drum Point Rd，Brick，NJ 08723，USA＆＃39;路线类型。

希望它有所帮助。
