Geotagging

« Back to Glossary Index

Geotagging is a digital process that involves adding geographical information to various types of media, such as photos or videos, in the form of metadata[4]. This location-specific data can include details like latitude and longitude coordinates, or even place names. The use of geotagging is widespread, prevalent in social media[1] platforms like Facebook[2] and Instagram[3], where it allows users to share their location and find nearby friends. In the realm of multimedia, it is used to enhance the information associated with photos. Techniques for geotagging vary based on the type of data, ranging from storing pixel coordinates to employing metadata. However, this process also poses certain risks and concerns, primarily related to privacy[5] and security[6]. Despite these risks, geotagging plays a significant role in improving search result accuracy, enabling location-based services, and supporting geographically organized data among other applications.

Terms definitions
1. social media. Social media is a broad term encompassing a variety of digital tools and platforms that facilitate the sharing of information and the creation of virtual communities. Emerging from early systems like PLATO and ARPANET, it has evolved into modern platforms like Facebook and Twitter. These platforms offer unique features that differentiate them from traditional media, including the ability for users to generate content and engage in dialogic communication. They cater to over 100 million users globally and offer different forms of services, such as messaging apps and collaborative content creation platforms. The use of social media has far-reaching impacts on individuals, society, and businesses, influencing everything from marketing practices to political processes. However, it's also associated with ethical concerns, such as the spread of misinformation and potential addiction.
2. Facebook ( Facebook ) Facebook, now known as Meta Platforms, is a major Internet company that started as a social networking platform. Founded by Mark Zuckerberg in 2004, Facebook expanded rapidly from Harvard to other universities and later to the general public, becoming a global phenomenon. It is known for its user-friendly interface and various features such as Groups, the Developer Platform, and Facebook Dating. Despite facing criticism for issues like privacy breaches and the spread of fake news, Facebook has remained a dominant player in the online world. It has made significant strides in the field of technology, including the development of its unique data storage system, the use of PHP for its platform, and the launch of the Hack programming language. In recent years, the company has shifted its focus to the metaverse, a virtual reality space where users can interact with a computer-generated environment.
Geotagging (Wikipedia)

Geotagging, or GeoTagging, is the process of adding geographical identification metadata to various media such as a geotagged photograph or video, websites, SMS messages, QR Codes or RSS feeds and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though they can also include altitude, bearing, distance, accuracy data, and place names, and perhaps a time stamp.

Geotagging can help users find a wide variety of location-specific information from a device. For instance, someone can find images taken near a given location by entering latitude and longitude coordinates into a suitable image search engine. Geotagging-enabled information services can also potentially be used to find location-based news, websites, or other resources. Geotagging can tell users the location of the content of a given picture or other media or the point of view, and conversely on some media platforms show media relevant to a given location.

The geographical location data used in geotagging can, in almost every case, be derived from the global positioning system, and based on a latitude/longitude-coordinate system that presents each location on the earth from 180° west through 180° east along the Equator and 90° north through 90° south along the prime meridian.[citation needed]

The related term geocoding refers to the process of taking non-coordinate-based geographical identifiers, such as a street address, and finding associated geographic coordinates (or vice versa for reverse geocoding). Such techniques can be used together with geotagging to provide alternative search techniques.[citation needed]
