Cartography can be seen as a form of communication currently undergoing a great deal of change. For centuries, cartography has been in the service of those in power, since map-making was such a highly specialized skill and only the royalty - and later, other governmental entities - could support the costly requirements of exploration, surveying, and gathering geographic data and producing maps. But with Geographic Information Systems, GPS, and the Internet, mapping is now in the hands of virtually anybody.VGI (volunteered geographic information) means that ordinary citizens collect and distribute geographic information via GPS and Internet mapping resources. Grass-roots community organizations and environmental advocates are using Geographic Information Science as a way of gathering information on their communities for organization of activities. This paper will trace developments in mapping and explore how maps can be used as a communicative tool.
