DESCRIPTION:Inverse problems are solved in geophysics and environmental sc
 iences\, basically in two different situations: either imaging or calibrat
 ion of predictive models. Roughly speaking\, "imaging" includes techniques
  to map the heterogeneity of the physical fields of interest and in essenc
 e it is a "diagnostic" tool. However\, in many fields of geophysics and of
  environmental sciences\, it is also necessary to forecast the future beha
 vior of natural systems with predictive models\, i.e.\, with "prognostic" 
 tools. In that case\, inverse problems are aimed to calibrate models.\nIn 
 this presentation\, a general framework for discrete inverse problems is r
 eviewed and discussed in order to emphasize the similarities and the diffe
 rences between the two situations for which inverse problems are solved\, 
 namely imaging and model calibration. In particular\, specific attention i
 s drawn to the relevance of the ultimate goals of the solution of inverse 
 problems for imaging and predictive modeling and to the role of field data
  and their processing.
