There’s an interesting analogy to the 15th and 16th Centuries when European explorers (or colonialists) were out sailing and mapping the globe. The world was not entirely known and mapped at that time. So it is today on the Internet. While many areas are highly developed and well documented in online mapping there are others that offer little information. Google has been trying to address that by opening up Earth and Maps to users through My Maps and collaborative map editing. Now comes Map Maker, which takes this to the next level.
