Where am I?
Answering this most basic of questions can represent a major challenge in developing countries. In regions with no maps, no addresses, sometimes no names, it is difficult to know location. And without location, it is impossible to meaningfully engage with the rest of the planet.
New technologies offer powerful solutions regarding location services.
First, and most fundamental, is global mapping. Google Maps, ESRI, and other services offer detailed traditional and satellite view maps. When conventional maps don’t exist in a location, researchers can now easily add them. For example, vaccine researchers at the Gates Foundation analyzed satellite images for regions not yet immunized — often because of inaccurate maps — in order to build accurate vaccination plans.
Second, new technologies can help define property rights. Over a billion households still live without property rights to their homes that are secure, registered, documented and tradable. These “hidden” rights are economically significant — likely exceeding $10 trillion in value. New registries are helping. The World Bank and others have invested in open cadastre systems. Drone technology can play a role. Even distributed blockchain technologies may become increasingly useful.
Finally, how does one describe their location if no addresses exist? By providing GPS coordinates of two nine digit numbers? A British firm called what3words has a clever solution. They divide the planet into a grid of 3 meters x 3 meters and have assigned each square a unique three word identifier (I’m currently writing, for example, from this beautiful corner of the planet: searching.colonialist.suggested).
