Deriving candidate indicators


Definition of Indicators

Indicators provide a metric of the state of (complex) systems or issues or for trends of their development, when measurements are repeated over time. It may be noted here that the term ‚monitoring’ implies repeated, if not regular or continuous, measuring of a particular variable used to support an indicator, as monitoring is aimed at addressing change, rather than observing a status quo. Indicators are useful tools to reduce a complex set of diverse data into a manageable set for policy decisions and to monitor changes that policy implementation may or may not effect (but it should be kept in mind that every process of indicator selection or aggregation inevitably includes both, a gain in clarity but also a loss of information). Indicators need to have a number of qualities and properties in order to be useful and they must have a clearly defined purpose.

The process of deriving candidate indicators within the EO-MINERS is a complex one and subject of a separate Task within WP1. This process is being described in detail in the related EO-MINERS deliverables D1.4 and D1.5. As is noted in D1.4, an indicator is only useful, when a method exists by which it can be measured. In consequence, this report matches available EO techniques to the indicators that are perceived as useful or important. This process results in narrowing down the range of indicators to those that can be treated by EO methods and further to those for which EO methods are available within the EO-MINERS project. This process of indicator selection is illustrated in the following Figure. Technology assessment and availability shape the final range of indicators to be covered within EO-MINERS.
