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; creating a data structure by using a computer to assign to each pixel in the digital image a value, based on a closest match in the color map, and a computer-interpolated geometry and location value, based on the geometry and location values; and transmitting the data structure to an interpretation application and creating a multi-dimensional geo-referenced data structure for interpretation.
