Volunteered Geographic Information and GIScience
نویسنده
چکیده
What are the research questions posed by Volunteered Geographic Information (VGI)? Does Geographic Information Science (GIScience) appropriately address them or does it need to shift its attention? I discuss changes to current research agendas, propose an arising grand challenge, and outline some specific new research challenges for scientists working within and outside GIScience.

An Introduction to OpenStreetMap in Geographic Information Science: Experiences, Research, and Applications
Recent years have seen new ways of collecting geographic information via the crowd rather than organizations. OpenStreetMap (OSM) is a prime example of this approach and has brought free access to a wealth of geographic information – for many parts of the world, for the first time. The strong growth in the last few years made more and more people consider it as a potential alternative to commer...
متن کاملExploiting Volunteered Geographic Information to describe Place
Traditional geographic information focuses on well-structured spatial data, generally based on either crisp objects or continuous fields, which usually reflect an institutional viewpoint and the purpose for which a dataset was collected. The attributes of such data are typically single valued at a given location or for a given object and thus, by definition, cannot reflect multiple viewpoints. ...
متن کاملComputing the semantic similarity of geographic terms using volunteered lexical definitions
Volunteered geographic information (VGI) is generated by heterogenous ‘information communities’ that co-operate to produce reusable units of geographic knowledge. A consensual lexicon is a key factor to enable this open production model. Lexical definitions help demarcate the boundaries of terms, forming a thin semantic ground on which knowledge can travel. In VGI, lexical definitions often app...
متن کاملValidation of Volunteered Geographic Information Landuse Change Using Satellite Imagery
Land use change monitoring is one of the main concerns of managers and urban planners due to human activities and unbalanced physical development in urban areas. In this paper, a combination of remote sensing data and volunteered geographic information was used to assess the quality of volunteered geographic information on land use and land cover changes monitoring. For this purpose, the ORBVIE...
متن کاملTowards a framework for automatic geographic feature extraction from Twitter
Interactive social media platforms offer a tremendous amount of volunteered, user-generated content (Flickr, Twitter, etc.). Together with volunteered geographic information (VGI) they potentially provide a valuable source of information which is increasingly recognized, but particularly in GIScience not utilized to its full potential. Twitter as one location-based social network in particular,...
