A Framework for Web and Mobile Volunteered Geographic Information Applications

This paper proposes a framework to be used in the creation of various volunteered geographic information applications, incorporating both Web-based tools and mobile applications (apps). The framework includes the elements required to customize the information collection, while using a unified structure and interface across Web and mobile platforms. We demonstrate the use of the proposed framewo...

A Framework for Implementing Volunteered Geographic Information Systems

In an effort to contribute to the conceptualization of the burgeoning field of Volunteered Geographic Information (VGI), we propose to review selected definitions and debates around Geographic Information Systems (GIS). “Traditional” geographic information emerges from the interplay of the components of GIS: hardware, software, data, and application, and it is shaped by the processing of geogra...

A Tale of Cities: Urban Biases in Volunteered Geographic Information

Geotagged tweets, Foursquare check-ins and other forms of volunteered geographic information (VGI) play a critical role in numerous studies and a large range of intelligent technologies. We show that three of the most commonly used sources of VGI – Twitter, Flickr, and Foursquare – are biased towards urban perspectives at the expense of rural ones. Utilizing a geostatistics-based approach, we d...

µ-shapes: Delineating urban neighborhoods using volunteered geographic information

Urban neighborhoods are a unique form of geography in that their boundaries rely on a social definition rather than a well-defined physical or administrative boundary. Currently, geographic gazetteers capture little more than then the centroid of a neighborhood, limiting potential applications of the data. In this paper, we present μ-shapes, an algorithm that employs fuzzy-set theory to model n...
