[edit] Geotagging
An interesting convergence of technologies is bringing maps and data together in ways that are transforming our understanding of history, geography, societal and political change, and more. Geotagging technologies include geocoding, the practice of adding geographical metadata (latitude, longitude, altitude, and/or placenames) to images, websites, or other media; geographic information systems (GIS), which store and analyze vast amounts of geographically-referenced information; and geolocation, the real-world location of a device connected to the Internet. Combinations of these technologies let us plot data against the landscape of the real world to visualize phenomena and datasets in ways that make spatial and temporal relationships transparent and obvious. More and more, geo-information is becoming a characteristic embedded in everything around us.
Geotagging is being used to annotate maps with notes about individual experiences and memories of a place. “Hyperlocal” information—minute details about a specific location in the form of everyday photographs, blog entries, and video clips—offers opportunities for research that were previously only available by actually living in the location in question. In the near future, digital photographs will automatically include geographic/locative information as they now include a time and date stamp; when uploaded to services like Flickr, the photos will “know” where they were taken. Geolocation is about revealing the real-world location of data, in space and in time; and its implications for research are profound.
[edit] Relevance for Teaching, Learning & Creative Expression
- Create interactive maps that use photographs and data tagged by others to draw a detailed picture of a place or event.
- Connect online content with real-world locations—and access the content using a mobile device for just-in-time delivery of information.
- Collect and mine geotagged information for research purposes.
[edit] Examples
- Researchers at the Pompeu Fabra University in Barcelona are mining the spatial-temporal data provided by geotagged Flickr photos of urban locations: http://www.girardin.org/fabien/tracing/
- The Center for Locative Media is geotagging three markers along the Mississippi Blues Trail in multiple media: http://www.locative-media.org/projects/C93/
- MIT’s Wiki City Rome project maps events and movement through the city in a 24-hour festival period using cell phone and other data: http://senseable.mit.edu/wikicity/rome/

Semapedia Adopts QR Code
(Leonard Low, Mobile Learning, December 8, 2006)
This blog post describes Semapedia, a way to create digitally-readable tags that can be stuck to real-world objects and read by a mobile device to bring up online content related to the location.
