Andrea Ballatore speaking at the University of Heidelberg
Giving a talk titled 'Volunteered geographic (mis)information? Measuring quality in crowdsourced maps'
Andrea Ballatore will be speaking at the Geographisches Institut at the University of Heidelberg on June 27th, giving a talk titled 'Volunteered geographic (mis)information? Measuring quality in crowdsourced maps'. You can read more information below.
The assessment of the quality of volunteered geographic information (VGI) is cornerstone to understand the fitness for purpose of data in many application domains. While most analyses focus on geometric and positional quality, little attention has been devoted to the interpretation of the data, i.e., the communication process through which consumers try to reconstruct the meaning of information intended by its producers. Interpretability is a notoriously ephemeral, culturally rooted, and context-dependent property of the data that concerns the conceptual quality of the vocabularies, schemas, ontologies, and documentation used to describe and annotate the geographic features of interest. To operationalize this dimension of quality in VGI and provide useful indicators to users and contributors, it is necessary to devise and test measures for conceptual accuracy, granularity, completeness, consistency, compliance, and richness. This framework is currently being implemented on OpenStreetMap, with plans for extension on Wikimapia.
