“…To address the critiques on traditional GIS, a range of qualitative GIS approaches have emerged in the postmodern era [25]. A diverse range of qualitative materials and situated perspectives (e.g., photographs, sketch maps, grounded visualizations, videos, personal experiences, preferences and perceptions, and narratives) can be incorporated into GIS.…”

“…It is often argued that traditional GIS rests on and amplifies an essentially positivist philosophical perspective [25]. According to Kwan [26], traditional GIS has been largely understood as a positivist or empiricist science, which is rooted in the quantitative revolution of geography and as such inherits the corresponding positivism or empiricism.…”

Integrated pest management (IPM) involves integrating multiple pest control methods based on site information obtained through inspection, monitoring, and reports. IPM has been deployed to achieve the judicious use of pesticides and has become one of the most important methods of securing agricultural productivity. Despite the efforts made to strengthen IPM during the past decades, overuse as well as indiscriminate use of pesticides is still common. This problem is particularly serious in underserved farming communities which suffer from ineffectiveness with respect to pest management information collection and dissemination. The recent development of volunteered geographic information (VGI) offers an opportunity to the general public to create and receive ubiquitous, cost-effective, and timely geospatial information. Therefore, this study proposes to enhance IPM through establishing a VGI-based IPM. As a starting point of this line of research, this study explored how such geospatial information can contribute to IPM enhancement. Based on this, a conceptual framework of VGI interaction was built to guide the establishment of VGI-based IPM. To implement VGI-based IPM, a mobile phone platform was developed. In addition, a case study was conducted in the town of Shuibian in Jiangxi province of China to demonstrate the effectiveness of the proposed approach. In the case study, by analyzing infestation incidents of an overwintering outbreak of striped rice stem borers voluntarily reported by farmers through mobile phones, spatiotemporal infestation patterns of the borers throughout the study area were revealed and disseminated to the farmers. These patterns include the dates and degree-days the pest infestations intensified, and the orientation or spatial structural variations of the clustering of the infestations. This case study showcased the unique merit of VGI in enhancing IPM, namely the acquisition of previously unrecorded spatial data in a cost-effective and real-time manner for discovering and disseminating previously unknown pest management knowledge.

“…In the philosophical sense, these new mapping practices attract attention in human geography and critical GIS for their collective, transient, and mutable nature (Schuurman 2006, Warf and Sui 2010, Elwood et al 2012, Leszczynski and Wilson 2013, Gerlach 2014, Perkins 2014. On the other hand, geographic information science (GIScience) has been engaging in formal ontology in the tradition of analytic philosophy and knowledge engineering, aiming at clarifying formally the logical constructs used to encode geographic information (Smith and Mark 2001, 2003, Kuhn 2003, Janowicz et al 2013.…”

Conceptualising the geographic world: the dimensions of negotiation in crowdsourced cartography

In crowdsourced cartographic projects, mappers coordinate their e↵orts through online tools to produce digital geospatial artefacts, such as maps and gazetteers, which were once the exclusive territory of professional surveyors and cartographers. In order to produce meaningful and coherent data, contributors need to negotiate a shared conceptualisation that defines the domain concepts, such as road, building, train station, forest, and lake, enabling the communication of geographic knowledge. Considering the OpenStreetMap Wiki website as a case study, this article investigates the nature of this negotiation, driven by a small group of mappers in a context of high contribution inequality. Despite the apparent consensus on the conceptualisation, the negotiation keeps unfolding in a tension between alternative representations, which are often incommensurable, i.e., hard to integrate and reconcile. In this study, we identify six complementary dimensions of incommensurability that recur in the negotiation: (i) ontology, (ii) cartography, (iii) culture and language, (iv) lexical definitions, (v) granularity, and (vi) semantic overload and duplication.

“…In geography, these phenomena have been variously and alternately referred to as 'volunteered geographic information' (VGI) Goodchild 2007), 'neogeography' (Graham 2010;Turner 2006;Warf and Sui 2010;Graham 2013a, 2013b), '(new) spatial media' (Crampton 2009;Elwood and Leszczynski 2012), and 'the geoweb,' (Elwood and Leszczynski 2011;Haklay et al 2008;Scharl and Tochtermann 2007). Here, we prefigure 'the geoweb' as we consider it to account for both new materialities and new practices.…”
