The term Volunteered Geographical Information
(VGI) refers to the use of the Internet to create, manage, and share geographical information which has been vol- untarily contributed by a community of users, also using the Internet. The set of techniques and tools used by those users is termed neogeography.
Neogeography has changed some fundamental ideas in cartography, since it has modified the traditional concept of geographical information (which was created by a very skilled few), its characteristics, or the role it played in certain fields. The following are some ideas about these changes and neogeography itself.
