import (
	"fmt"

	"github.com/toyo/go-latlong"
)

func main() {
	l := latlong.NewRect(35, 135, 0.1, 0.1) // N35+-0.05 Deg. E135+-0.05 Deg.

	fmt.Println(l.GridLocator()) // shows GridLocator. https://en.wikipedia.org/wiki/Maidenhead_Locator_System
	fmt.Println(l.GeoHash())     // shows GeoHash. http://geohash.org/
	fmt.Println(l.String())      // shows lat/long in string.
}
