Over the history of remote sensing, the complexity and volume of data sets have increased unremittingly. The complexity of the data sets has led to the need for more descriptive metadata. The volume, resulting from both increased precision and range in the data sets, has led to the need for efficient data and portable handling techniques. Further, the precision calls for greater detail in describing and documenting the manner in which the data was collected and calibrated. This paper describes one view of the optimal product design for NPOESS requirements.
