🌊 Check whether a geographic coordinate is in the sea or not on the earth.
Click on the map to see a live preview.
Given the latitude and longitude coordinates this package returns whether the point fall into a sea/ocean or not.
The package internally uses @geo-maps/earth-seas map with 10m resolution. The accuracy of the map has not been tested but the demo allows you to actually test it manually by just clicking on the map to see what it returns.

$ npm install --save is-seaYou can query any (lat,lng) pair on the earth.
const isSea = require('is-sea');
// Query a point in Italy.
isSea.get(41.9028, 12.4964);
// => false
// Query a point somewhere in Atlantic Ocean.
isSea.get(40, -40);
// => trueReturns wheather the given point is in the sea or not.
Returns: Array.<string> - True if the point is in the sea, false otherwise.
| Param | Type | Description |
