Google has created an online service called mapmaker. With mapmaker you can contribute to the Google maps, at this time in selected areas in the world. On top of the satellite images that are provided, users may annotate directions, add names of roads, local stores, and other point of interest. This is than moderated and can be included in the Google community. By using this system, Google goes to a next level in what can describe teh 'crowd sourcing' model: using local knowledge and capitalising on it.
