Lots of ways this technology can be used in terms of plotting resources over time, locations as well as use: oil and other none renewable as well as bio resources...and of course global warming, hurricanes, thermohaline patterns ...even moving back into geologic time.  

Population growth would work well...as would economic realities. For those interested in the housing bubble over time, hmmmmmm.   Makes one think, doesn't it.  Or even global shifts in manufacturing centers over time.  Nothing like seeing the world as a single ball.

I envision a number of databases, each of which can be overlaid with another. Imagine being able to see food production and population growth...or bio depletion together with land despoilment...all on one little marble.  

Ultimately, as more and more databases are added and updated, we could actually see the major patterns evolving.  No need to constantly recreate them.  Like Wikepedia, the data could be upgraded as we learn more and more.

Ultimately, the user would be able to combine any set of databases that interests him...and see their developments through time.

Now we are really looking at how to use the new technology.

Having had 5 Years in the GIS and Digital Mapping field its all great and fine if the Data sets are good.

Sorry I was in the Hospital for a Blood Clot that blocked both lungs, Gone for the turn of the new year, so sad not to see all those nice threads on coal and US production.

But modeling all those neat things depends greatly on the Data you have.  We have pretty good data on the Gulf coast, but every season we have to update it.  Nothing is as it seems until you get the right data for it, then it changes faster than you can plot it out into a new map.
