Uncertainty in Determining the Extension of Anomalous Zones of Spatial Environmental Variables

Abstract: Spatial anomalies, extremes and outliers are of great interest in environmental studies, because they may represent zones of hazard or of valuable resources. Estimating risks or benefits associated with them is therefore closely related to estimating their spatial extension. Since it is estimated from an inevitably finite number of samples any estimate has an associated uncertainty. In this contribution I want to present some ideas how the problem could be tackled and show results for a particular simple case.

Keywords: spatial field, anomaly, uncertainty
