1. A computer implemented method for converting a digital image into a multi-dimensional geo-referenced data structure, the method comprising: storing a prepared digital image on a computer readable medium in a computer readable format; defining a color map comprising values for the prepared digital image; defining geometry and location values for the prepared digital image; and creating a multi-dimensional geo-referenced data structure for interpretation, wherein the multi-dimensional geo-reference data structure comprises horizon data and the horizon data is further converted to a seismic application to create a 3-dimensional seismic data structure, by using a computer to assign to each pixel in the digital image a value, based on a closet match in the color map, and a computer-interpolated geometry and location value, based on the geometry and location values.
