Always come across the words Geotagging and geofencing. Hence i would like to note down the different of these words in my blog. Both are related to location-based technologies, but they serve different purposes. Here's an explanation of each term:
Geotagging
Geotagging is the process of adding geographical metadata, such as latitude and longitude coordinates, to various forms of media such as photos, videos, or text. It enables the identification and organization of content based on its specific location. Geotagging can be done manually, where users add location information to their content, or automatically through GPS-enabled devices that capture the coordinates at the time of creation.
For example, when you take a photo with a smartphone, the device can automatically embed the GPS coordinates into the image file, allowing you to view the location where the photo was taken on a map.
Geofencing
Geofencing is a location-based service that involves creating virtual boundaries or fences around a specific geographic area. These boundaries can be defined using GPS, RFID (Radio Frequency Identification), or cellular/Wi-Fi network signals. When a device or user enters or exits a geofenced area, predefined actions or notifications can be triggered.
Geofencing is commonly used in various applications. For instance, retail businesses can set up geofences around their stores. When a customer with a mobile app enters the geofenced area, they may receive location-specific offers or notifications. Geofencing can also be utilized for security purposes, where an alert is sent if an unauthorized device enters a restricted area.
In summary, geotagging is the process of attaching location metadata to media content, while geofencing involves creating virtual boundaries to trigger actions or notifications based on the user's entry or exit from a specific area.
