The epistemology(s) of volunteered geographic information: a critique [PDF]

open access: yesGeo: Geography and Environment, 2015
Numerous exegeses have been written about the epistemologies of volunteered geographic information (VGI). We contend that VGI is itself a socially constructed epistemology crafted in the discipline of geography, which when re‐examined, does not sit comfortably with either GIScience or critical GIS scholarship.

Using textual volunteered geographic information to model nature-based activities: A case study from Aotearoa New Zealand

open access: yesJournal of Spatial Information Science, 2021
A boom in volunteered geographic information has led to extensive data-driven exploration and modeling of places. While many studies have used such data to explore human-environment interaction in urban settings, few have investigated natural, non-urban ...

VOLUNTEER GEOGRAPHIC INFORMATION IN AFRICA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Abstract. During the past few years much effort has been put into developing community-based methods to capture and analyze a large amount of data in a systematic manner. This new source of geo-referenced data could be very important throughout Africa where crowd sourcing activities or volunteered geographic information (VGI) enhance participation and ...

Barriers to the Localness of Volunteered Geographic Information [PDF]

open access: yesProceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems, 2015
Localness is an oft-cited benefit of volunteered geographic information (VGI). This study examines whether localness is a constant, universally shared benefit of VGI, or one that varies depending on the context in which it is produced. Focusing on articles about geographic entities (e.g. cities, points of interest) in 79 language editions of Wikipedia,

From Topic Networks to Distributed Cognitive Maps: Zipfian Topic Universes in the Area of Volunteered Geographic Information [PDF]

open access: yesComplex, 2020
Are nearby places (e.g., cities) described by related words? In this article, we transfer this research question in the field of lexical encoding of geographic information onto the level of intertextuality.
