Definition

Calibration. The process of quantitatively defining the system responses, under specified conditions, to known, controlled signal inputs. The result of a calibration permits either the assignment of values of measurands to the system output or the determination of corrections with respect to the system output (Joint Committee for Guides in Metrology JCGM (includes ISO) 2008; Randa et al., 2008; CEOS Working Group on Calibration and Validation, 2012).

Validation. The process of assessing, by independent means, the quality of the data products derived from the system outputs. The quality is determined with respect to the specified requirements (Joint Committee for Guides in Metrology JCGM (includes ISO) 2008; Randa et al., 2008; CEOS Working Group on Calibration and Validation, 2012).

Introduction

The value of remotely sensed data products, in the scientific sense in particular, is determined by how well the characteristics of a product are known (e.g., Platt and...
