Once the coin to geocordinate algorithm has been figured out, i imagine it shouldn't be difficult to use Google Earth overlays to visualize the data.
That will be a very intuitive and appealing concept to ordinary people. I still prefer treating all earth's surface equally, instead of trying to figure out which is land, which is ocean.
But to support this algorithm, it will require some fundamental changes and it will increase the complexity of the system. Using real world analogy, in current bitcoin system there's a gold "pool" with 21 million ounces gold in there, each btc address is a warehouse receipt against this pool, it only tells you how much
you own but not what
particular gold ounce/bullion you own.
To track every 1E-8 ounce of gold, more information need to be added to each transaction, new mechanisms are needed, such as uniqueness ownership validation, bitdust ID clumping and consolidation etc. There will be a global database recording the ownership of all "bitdust" in existence.
Besides for the purpose of visualization, I am still trying to figure out what other benefit this feature can bring about. Otherwise it may actually be a step backward. In today's world, financial institutions transact billions dollars each day without needing to know the serial numbers on those phantom dollar bills.
