Enhancing the management of quality of VGI: contributions from context and task modelling

Abstract

The ENERGIC COST ACTION targets the usage of Volunteered Geographical Information (VGI) and of crowd sourced geographical information (CSGI) in scientific applications. One challenge addressed in this action is data quality management. Data quality management has been addressed for several years with respect to classical geographical data, by operational bodies like the National Mapping Agencies and by scientists mainly from the geographical information science community. The issues they tackle are also relevant in the context of volunteered and user generated data, for example managing the lack of a universal data model about geographical space and the unavoidable heterogeneities between geographical
