There is no country located 30 degrees south latitude and 60 degrees east longitude. The islands that are nearest to these coordinates are Reunion, a province of France, and the country of Mauritius.
When using the latitudes and the longitudes in locating places on a map or globe, one should start by locating the zero coordinates, or the point from which one should start counting. Zero degrees latitude is the same as the equator, the line dividing the Earth into the Northern and Southern hemispheres. Zero degrees longitude refers to the prime meridian, where the Royal Observatory, Greenwich, is located.
