1. A method for creating a physical property model representative of a physical property of a region, comprising: transforming information from a model domain that represents the physical property model into simulated data in a data domain, the data domain comprising simulated data and measured data representative of a plurality of observations of the region, wherein the transforming is performed using a computer; determining an areal misfit between the simulated data and the measured data representative of the plurality of observations of the region, wherein areal misfit means misfit determined at a plurality of locations within the region, said locations each being specified by at least one of a receiver location and a source location; performing an evaluation of the areal misfit based on known criteria; and adjusting data in the data domain or information in the model domain corresponding to a region in the model domain based on the evaluation of the areal misfit.
