onwater.io golang API wrapper

Onwater.io is an API for determining if a point (latitude and longitude) is on water or land. This library is a small wrapper around for working with that API.

Installation

go get github.com/andy/onwater

Example

package main

import (
  "context"
  "os"

  "github.com/andy/onwater"
)

func main() {
  client := onwater.New(os.Getenv("ONWATER_API_KEY")) // "" for an unpaid API Key with rate limits

  isWater, err := client.OnWater(context.Background(), 55.753675, 37.621339)
  if err != nil {
    // handle error which is most likely a http error or reply status code was not 200
  }

  if isWater {
    // lat/lng is on water
  } else {
    // lat/lng is on land
  }
}

Note that there is also client.OnLand which is just an opposite for client.OnWater
