The document discusses the characteristics of different stakeholders in user-generated geographic information (VGI). It identifies four main stakeholder groups: consumers, special interest mapping groups, local communities, and professionals. For each group, it outlines their motivations, needs, and perspectives regarding VGI data completeness, freedom of use, community focus, and how VGI can add value when integrated with traditional geographic data. The document concludes that stakeholder usability depends on both functional and human factors, and that people are motivated to contribute through a sense of community and helping others.
