Managing Sensor Data Uncertainty: a data quality approach

International audienceWith an increasingly technological improvement, sensors infrastructure actually supports many current and promising environmental applications. Environmental Monitoring Systems built on such sensors removes geographical, temporal and other restraints while increasing both the coverage and the quality of real world understanding. However, a main issue for such applications is the uncertainty of data coming from sensors, which may impact experts’ decisions. In this paper, we address this problem with an approach dedicated to provide environmental monitoring applications and users with data quality information
