Information Quality

Welcome to the ESIP Information Quality Cluster

The objective of IQ cluster is to bring together people from various disciplines to assess aspects of quality of remote sensing data. We will be learning and sharing best practices with a goal to build a framework for consistent capture, harmonization and presentation of data quality for the purposes of climate change studies, earth science and applications. This wikispace will be taking shape in the coming months to describe activities within the ESIP Federation related to Information Quality.

Events and Activities

Regular monthly telecons will be will be established soon.
