I'm looking for implementations of spatial tag clouds or "tag maps". Some papers I found talk about a Yahoo Tag Maps API, but I couldn't find any such thing.

I'd prefer OpenLayers-based solutions, but others would be interesting too.

Edit: Example images can be found at http://www.soi.city.ac.uk/~sbbb717/go2/iv_figs/, e.g:

  • could you post an example/link of such a map? – radek Dec 13 '10 at 14:05
  • One of the guys here at Esri Australia created one for geotagging #tags on twitter. Unfortunately was a WPF app which only ran on the desktop. I could ask him to put it out – CDBrown Dec 16 '10 at 8:38

The key paper describing this work is Interactive Tag Maps and Tag Clouds for the Multiscale Exploration of Large Spatio-temporal Datasets, by: Aidan Slingsby, Jason Dykes, Jo Wood, Keith Clarke, In IV '07: Proceedings of the 11th International Conference Information Visualization (2007), pp. 497-504. doi:10.1109/IV.2007.71 http://www.citeulike.org/user/ianturton/article/2040316. However I can't find a reference to the actual tag-map applet they used in the paper (and I think I pointed that out when I reviewed the paper, so much for peer-review).

  • Thanks Mapperz, but these don't look quite right ... I'd expect differently sized labels depending on how many same-tagged features are found in close proximity. – underdark Dec 13 '10 at 21:09

Some of the things we talk about in HEALTH GeoJunction: place-time-concept browsing of health publications http://www.ij-healthgeographics.com/content/9/1/23 could be relevant. We didn't put the tags on the map but we do discuss how to build a tag cloud with spatial aspects.

The actual app is at http://www.apps.geovista.psu.edu/hgj/# (but you will need flash enabled).

  • I keep getting a 'No data returned' error in the flash app. – underdark Dec 16 '10 at 9:42
  • Sorry about that the database password had expired which took some tracking down. – Ian Turton Dec 16 '10 at 20:50

This is Yahoo's Flash-based solution: http://tagmaps.research.yahoo.com/worldexplorer.php

Too bad, the API link is broken.
