Navigation about the world (planet Earth) uses the concepts of Latitude and Longitude to determine position on surface; these dimensions being in degrees, a dissection of 360 (harking back to ancient astronomers). Hence, you can be up to 180 degrees East or West of 0 (Greenwich), and up to 90 degrees North or South of the Equator - a system like being AM or PM in daily time. Yet there is Army time, the 24-hour clock, which has its uses, though not everyone is enamored of it. Likewise, it is possible to devise a navigational equivalent, whereby any place on the globe would have unique coordinates, being purely numeric. Starting at the Sao Tome-Accra Triangle (0,0), we can go the full 360 degrees Eastward, and, also, full 360 Northward - though Southward, once the Pole was reached. There would be no need to specify East, etc, once such direction was commonly accepted. Nor Latitude or Longitude, if Latitude is always stated first. This would have the benefit of putting both Latitude and Longitude within the same large numerical range. (A same-range effect may be achieved by dividing the globe into spherical quadrants, so each L&L was within 90 degrees.) The Earth is an oblate spheroid, but this is standard, whatever system is used.
