What Volunteered Geographic Information is (good for) - designing a methodology for comparative analysis of existing applications to classify VGI and its uses

Volunteered Geographie Information (VGI) is the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals, and is regarded by the authors as an important component of Community Remote Sensing. What is currently lacking is a systematic framework that classifies the myriad of VGI products and sources. In this paper we propose a methodology based on business process modeling that allows the description of VGI applications, which can be used to perform a comparative analysis of VGI sources.
