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

摘要: In crowdsourced cartographic projects, mappers coordinate their efforts through online tools to produce digital geospatial artefacts, such as maps and gazetteers, which were once the exclusive territory of professional surveyors cartographers. order meaningful coherent data, contributors need negotiate a shared conceptualisation that defines domain concepts, road, building, train station, forest lake, enabling communication geographic knowledge. Considering OpenStreetMap Wiki website case study, this article investigates nature negotiation, driven by small group in context high contribution inequality. Despite apparent consensus on conceptualisation, negotiation keeps unfolding tension between alternative representations, are often incommensurable, i.e., hard integrate reconcile. we identify six complementary dimensions incommensurability recur negotiation: 1 ontology, 2 cartography, 3 culture language, 4 lexical definitions, 5 granularity, 6 semantic overload duplication.
