Geo-tags may also be applied to digital output and communications such as tweets or status updates on social media. Geo-tagging is the process of attaching location information in the form of geographical metadata to digital media like web sites, videos, and photographs. The additional information provided by metadata can be useful – but in the wrong hands, or communicated in the wrong way, it can also be a problem. This metadata as it’s known describes not only resources, web pages, and database entries, but also objects – including some of the artifacts that we create every day. With the internet and wireless communications playing such a large part in our lives, there’s a lot of information around these days – and much of it is simply data about data.
