Data having all of the same characteristics (source or class of source, processing level, resolution, etc.) but different independent variable ranges and/or responding to a specific need are normally considered part of a single data set. A data set is typically composed by products from several missions, gathered together to respond to the overall coverage or revisit requirements from a specific group of users. </p><p>In the context of EO data preservation a data set consists of the data records and their <em>associated knowledge (information, tools)</em>.
