What is Geolocation?


Everything on the Earth’s surface has a location that can be expressed with just two coordinates. Using the new classes of geolocation tools, it is very easy to determine and capture the exact location of physical objects — as well as capturing the location where digital media such as photographs and video are taken. The other side of this coin is that it is also becoming easier to work with the geolocative data thus captured: it can be plotted on maps; combined with data about other events, objects, or people; graphed; charted; or manipulated in myriad ways. Indeed, such data are leading to entirely new forms of mapping. Devices we commonly carry with us increasingly have the ability to know where they (and, consequently, we) are, and to record our coordinates as we take photographs, talk to friends, or post updates to social networking websites. The transparency of this group of technologies — they are increasingly embedded in all sorts of devices and technologies — is making them very much an essential part of our lives.
