It's not just easier, GPS is vastly more reliable and accurate than almost any other method of navigation. So much so that it's starting to be relied on in many industries. For example, airplanes are starting to move away from a radar based method of air traffic control to a GPS based system. Every airplane will simply continuously transmit its GPS coordinates as part of its transponder message. From this you can create a highly accurate map of where every plane is, except much more accurate than with radar.
