I suppose then it becomes a question of having providers publish temporal data. Who will publish this kind of data? Perhaps there could be an OpenStreetMap / Wikipedia style initiative to build a digital model of history. Or perhaps this is the kind of thing Freebase could do as is. Let's say we wanted to depict the conquest of the Americas. We could show native tribal zones, the impact of early Europeans, disease and the like; how this affected distribution and habitat. I imagine seeing tribes represented as splotchy polygons that change shape and size over time, and I imagine these extents being pinned down temporally by little markers that indicate carbon-dated archeological fragments recovered in the field, and or anecdotal stories passed down as legend... Changing the lens to focus on say animal populations or plants, one could see say horses spread across North America again, or see the agribiz industries grow... Anyway idle speculation... more than any real concerted plan to actually Do Something. - me On Wed, Apr 8, 2009 at 9:22 AM, Andrew Turner <[email protected]> wrote: > > Tyler Erickson wrote: > > p.s. one thing I REALLY would like – because of how much it confuses casual > users – is the ability to control whether the time slider is ON or not, from > a KML feed when it’s launched.
