Apparently Google Earth already has features for such things and rather than roll my own I'd like to use their feature for the project I envisioned. Some benefits of using Time Aware KML are:
- Putting all/several models in one KML file. My other approach would have relied on separate files for separate date ranges
What was my idea project, you ask? A short while back, while reading European history in preparation for my trip to Italy, I kept reading about such-and-such people who moved or migrated from point A to point B, then later to point C, and D. Keeping track of it all in my head was getting difficult, so I wished for an applet that could let me track the populations and their neighbors over time. The problem was I could not think of a platform that would make creating this applet easy to build and easy to distribute. And voila! Google Earth is perfect for it.
I hope to have a sample app up sometime soon to show you the idea. I think the educational value is immense, and so far, the only site I've found that was even close to using the technology for this is:
Digital Archaeological Atlas of the Holy Land
However, I think using a fluid time-progression of empire geometries would be a lot more engaging for students or others with an interest in the human geography.
