Abstract or Summary
  • Sharing data across geographic and jurisdictional boundaries is one way that Pacific Northwest resource managers, policy makers, and scientists can improve their ability to make decisions about natural resources, including salmonid recovery, aquatic resource status, and watershed management. With the establishment of centralized natural resource databases and movement toward standard monitoring and sampling methods, data aggregation could be used to create regional, state-wide, or population-level assessments. Natural resource data are frequently collected in localized or spatially discontinuous patterns, and are typically gathered in surveys or studies targeted at a narrowly-focused set of questions. Inevitably, new questions arise that make it desirable to combine data sets that have different variables, or to amass data from spatially disconnected studies to address more regionalized questions. Data aggregation techniques could be used to combine disparate data sets and for ‘regionalizing’ data from finer to coarser scales. The goal of this report is to discuss the kinds of data that can be aggregated with suitable techniques, and the consequences of improper aggregation.
