Geotagging, also known as geocoding, is the process of adding geographical identification metadata to various forms of media such as photos, videos, websites, SMS messages, QR Codes, or RSS feeds. This data usually consists of latitude and longitude coordinates, though it can also include altitude, distance, place names, and more.

Geotagging can help users find a variety of location-specific information. For instance, one can find images taken near a given location by entering latitude and longitude coordinates into a geotagging-enabled image search engine. Geotagging can also be used to produce location-based news, websites, or other resources.

Geotagged photographs, for example, are increasingly used in social media and photo sharing platforms. When you take a picture with a GPS-enabled camera or smartphone, it can automatically record where the photo was taken, and you can share this information when you upload the photo to platforms like Instagram or Facebook.

While geotagging can be beneficial, it also raises privacy concerns. If location information is shared unintentionally, it could potentially be used by malicious actors for purposes such as stalking or determining when a person’s home is unoccupied. Therefore, it’s essential to be aware of when and how you’re sharing geotagged information.
