Volunteered Geographic Information (VGI) systems and their interactions with Geospatial Semantic Web
2015With the development of the Internet, especially Web 2.0, user-generated contents such as “Volunteered Geographic Information (VGI)” have gained attention and generated a lot of information over the Web. This chapter introduces the basic information about VGI and presents that VGI (or crowd-sourcing) applications have proven useful for gathering and ...

Our contribution concerns the use of Social Media Geographic Information (SMGI) as an emergent pluralist source of information which may find valuable application in spatial planning and Geodesign. On the base of empirical research, the authors propose a tentative framework for SMGI Analytics in spatial planning.

Owing to the rapid development of geospatial and mobile communication technologies in recent years, acquisition of high-quality spatial and temporal information has become much more efficient and cost effective than before. As a result, many researchers deem that data collected by volunteers with little training can be used for scientific researches if

Volunteered Geographic Information (VGI) is being collected worldwide and may be a source for authoritative data providers such as national mapping organizations. In order to evaluate the usability of these data as part of an authoritative dataset, it is first necessary to understand the quality and reliability of the data.
