Interactive display of humanitarian and development project data

With such a potential wealth of information relating to our global activity, it begs the question how do we best communicate this information?  With such a significant effort involved in capturing this information, how can we ensure that we add value by communicating it and learning from it in the most effective way?   How can we tell a story with the information we have at our disposal?  One option is to build an interactive application which can be either web-enabled or stand-alone.  What I envisage is users being presented with a world map, with the countries where Oxfam is working highlighted.  Users could then click on a country, whereby the application zooms in, and displays information (e.g. text and graphs) relating to the number of beneficiaries in each of the data categories available.  Project locations, together with associated project details, could also be toggled on and off.  Essentially the tool should be: user-friendly; allow information to be gleaned quickly and easily; employ excellent interactive presentation; allow the option of adding various layers of information to further enrich analysis; and potentially link in with Google Maps (or other system) to show detailed location information around project sites. This problem will be presented by a subject matter expert, in person, at the Oxford (UK) event.
