This is a very cool implementation of Google maps, built by Joseph Boutilier (at 18 the youngest candidate in the current Victoria municipal election). He took a map of Victoria and added geo-links to connect specific sites with specific issues (and his proposed policies/ approaches). Very nice work.

"The main principle of MapTube is that shared maps can be overlayed to compare data visually. For example, to see a map of the London Underground overlayed on top of a map of population you simply go to the search page and enter the keywords "tube" and "population". Then click on the two relevant maps to add them."

This has potential for some really fine-grained mapping, specific to local place.
