DESCRIPTION:Inverse problems are solved in geophysics and envi
 ronmental sciences\, basically in two different si
 tuations: either imaging or calibration of predict
 ive models. Roughly speaking\, "imaging" includes 
 techniques to map the heterogeneity of the physica
 l fields of interest and in essence it is a "diagn
 ostic" tool. However\, in many fields of geophysic
 s and of environmental sciences\, it is also neces
 sary to forecast the future behavior of natural sy
 stems with predictive models\, i.e.\, with "progno
 stic" tools. In that case\, inverse problems are a
 imed to calibrate models.\nIn this presentation\, 
 a general framework for discrete inverse problems 
 is reviewed and discussed in order to emphasize th
 e similarities and the differences between the two
  situations for which inverse problems are solved\
 , namely imaging and model calibration. In particu
 lar\, specific attention is drawn to the relevance
  of the ultimate goals of the solution of inverse 
 problems for imaging and predictive modeling and t
 o the role of field data and their processing.
