Image copyright Google Maps Image caption The image above shows the exact location of a beach at Porthall, near Porthill, on the east coast of Ireland, and how far it’s from the city of Belfast.
The image is in the format of latitude/longitude.
You can see the area of land in the image, as well as the elevation and distance to each point.
You could also see that the area is not as far away from Porthalor, a city in Co Clare, as the image suggests.
