visual taxonomy of geo-referenced data 0.2

Referring to this preliminary introduction, I’ve been keeping on analysing case studies on geo-referenced visualizations and interactive interfaces exploring territorial data.
A preview of the matrix at the current stage follows.

(I’m constantly integrating the matrix with new interesting projects I find, which I store here)
I’m basing my analysis on famous academic (and not) categorizations of visualizations, trying to interpret and cross them in a meaningful way for my purposes.
I analysed the work of different authors, among which: Jeffrey Heer and Ben Shneiderman (with their taxonomy of interactive dynamics for visual analysis) William Bevington (a visualization-based taxonomy for information representation), John Campbell (Map Use and Analysis) and Edward Segel and Jeffrey Heer again with their famous Narrative Visualization: Telling stories with Data paper.

Case studies has been mainly divided into topics / issue they address:

Main categories through which the analysis is directed are:
– data handling (data harvesting / data source / data aggregation methods)
– main interface (view / interactivity / scale / places)
– data display (base / superficie / side)
– interactivity (data exploration / view manipulation / exporting options / interactive elements)

An analysis of some interesting clusters made possible by the crossing of different categories will follow.
During the following months as DensityDesign we’re planning to review the material with international visualization experts, to create an interactive repository of categorized case studies, and to publish the final taxonomy.

Any help, advice or further references is more than welcome; if you want to know more about this work, please write me.
