Radiometric balancing is a time-consuming and difficult process. Imagery is usually balanced locally, with nearby photos, and globally, with all the photos. The balancing becomes more difficult as the number of photos increases, which is influenced by the spatial resolution and area of coverage. Furthermore, the result of the balancing process is subjective to the viewer and the scale at which the data is viewed.

radiometric balancing: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).
