I love what openstreetmap has set up, and I would like to help take the idea further. With openstreetmap, the focus is on "lines" for transportation infrastructure. Is there any open source technology that can be deployed that allows users to create polygons (shapes), and change their representation, including "time" animation functions?
What I am envisioning is something where a user can create and/or manipulate polygons to show everything from population density, to rainfall and climate change, to market flows, to historical maps that can be animated. - In the case of population density, a wiki user could simply enter the latest data, say at the county level of the US, and be able to view it with increasing shades of red. The user can then view data with increasing or decreasing granularity, and create a variety of visual representations. - In the case of historical maps, people could take detailed information about, say, border changes, and show how the borders changed over time.
