Geotagging is the process of adding geographical information, such as latitude and longitude coordinates, to a photograph. Some synonyms for geotag include location tagging, GPS tagging, geo referencing, and geo coding. These terms are all used to describe the same process of adding location data to digital media. Geotagging is particularly useful for photographers, social media users, and researchers who want to document the precise location where a photo was taken. It can also be used for tracking wildlife, studying weather patterns, or mapping out hiking trails. Overall, geotagging is a powerful tool for adding context and meaning to digital media.
