     Today, maps are most often used when they are not printed. Although printed maps still exist, more popular forms of navigation include GPS and Google Maps or Google Street View. GPS, which stands for Global Positioning System, lets a person know where they are on the earth. This is possible through the satellites orbiting earth. A GPS can send radio signals to an orbiting satellite to detect where the satellite is in orbit. This information reflects back to the sender and allows the GPS to know its position on the globe [1]. This process borrows from the concepts of time keeping and angle measurements used during navigation of Turner's time. A GPS is a more advanced form of angle-measurement navigation because its constant reflecting of radio waves to satellites allow people to know where they are and where they are going even when they are still in motion. Because of this, many people of the modern age use GPS to coordinate directions rather than bring a printed map on their outings. Another way people view modern day maps is Google Street View. Google Street View is a series of pictures taken from a 360 degree camera that looks much like a ball. These images are pieced together much like the mosaicing process of map making. Google uses GPS technology to link the new, giant picture to a location so a person visiting Google Maps could click on a location and see a 360 degree image of where they are going. More than this, the images are taken from moving cameras so the navigator can visualize what their entire trip will look like before ever beginning the path in the first place. Google Street View uses cameras attached to cars, tricycles, snowmobiles, trekkers, and trolleys so viewers can see images of not only streets but also wilderness and the insides of buildings [2].
