In days past, photographers had to rely on their memory to answer the question “where did I take this shot?”. Not so any more. Geotagging is fast becoming popular in the days of digital photography. By definition, Geotagging is the process of adding a form of geospatial geographical identification metadata to your images. It can also be added to other media like websites or RSS feeds. This metadata almost always consists of latitude and longitude coordinates; although it can sometimes also include things like altitude, bearing, or even location names depending on how specific you want to get.

Geotagging can also be useful if you are looking for location-specific information. For example, you are trying to find images taken near Red Rock Canyon. You simply enter the latitude and longitude coordinates into a Geotagging-enabled image search engine. There you go! These same search engines can also be used to locate location-based news, websites and more.

Whenever you buy a GPS, they come with preloaded maps, basically if you buy one in the United States, you will get maps of the U.S., and neighboring countries and if you buy a GPS in Europe, you will get European maps. What happens if maps get updated? To update GPS maps it usually costs a lot of money, and if you move far away you will need a new GPS. This new service aims at stealing maps from sites and saves it and uses those. You would think such a service would cost a lot of money, but in fact, it only costs $9.
