1. A method of constructing a data model defined by a plurality of parameters, comprising: collecting a plurality of field measurements, each of said plurality of field measurements bearing an indirect relationship to a first subset of said plurality of parameters; transforming said collected plurality of field measurements into a selected pattern space; determining values for said first subset of said plurality of parameters from said collected plurality of field measurements after transformation, of said collected plurality of field measurements, into said selected pattern space; and constructing said data model using said determined values for said first subset of parameters.
