A European proposal for terms of reference in data fusion
Résumé
Data fusion is a subject becoming increasingly relevant as scientists try to extract more and more information from remotely sensed data. Archives are growing, as well as the number of space missions devoted to Earth observation. It is generally correct to assume that improvements in terms of classification error probability, rejection rate, and interpretation robustness, can only be achieved at the expenses of additional independent data delivered by more separate sensors. Sensor data fusion allows to formalise the combination of these measurements, as well as to monitor the quality of information in the course of the fusion process. A Special Group of Interest ‘data fusion' has been established jointly within the European Association of the Remote Sensing Laboratories (EARSeL) and the French Society for Electricity and Electronics (SEE). This Group has defined several major tasks to be handled in order to increase our understanding and use of data fusion. One of these tasks is the establishment of terms of reference that are accepted by both the scientific and the industrial communities at least in Europe. A definition of the data fusion is proposed, which allows to set up a conceptual approach to the fusion of Earth observation data by putting an emphasis on the framework and on the fundamentals in remote sensing underlying data fusion. Several other definitions are given which are useful to describe any problem of data fusion.
