1. A method for accessing, processing, and representing information whereby a data representation is generated in correspondence with a plurality of data-point projections, each of said data-point projections extending from respective data-point coordinates to intersect an approximating relationship, intersections of said data-point projections with said approximating relationship substantially establishing respective inversion-conforming data sets which comprise projected coordinates for points that conform to a corresponding data inversion at respective said intersections, each of said sets of projected coordinates comprising a respective subset of said data-point coordinates and at least one parametrically determined variable measure, each said determined variable measure being determined in correspondence with said approximating relationship and at least one data-point coordinate of said respective subset, said approximating relationship establishing respective correspondence between said at least one data-point coordinate and said at least one parametrically determined variable measure, said approximating relationship being determined in correspondence with a parametric approximative form and at least one parameter estimate, and said data representation being rendered in correspondence with said parametric approximative form and at least one inversion parameter estimate, said method comprising: activating means for said accessing, processing, and representing information whereby at least one form of inversion-conforming data sets processing is effectuated; accessing provided data; establishing said parametric approximative form; establishing at least one respective inversion parameter estimate; determining said approximating relationship as related to said parametric approximative form and said at least one respective inversion parameter estimate; and effectuating said at least one form of inversion-conforming data sets processing; said means for accessing, processing, and representing information comprising: a control system; and said control system being configured for providing said activating, said effectuating, and said representing information; said effectuating including implementing and effecting at least one form of parameter estimating in correspondence with said provided data whereby said at least one inversion parameter estimate is generated.
