<p>An improved method for recognizing and compAring features of attribute data expressed in a 3D data survey involves: extracting, mapping, color coding and displaying 3D data for at least one attribute. Preferably, the data is based on tomographic paths. The tomographic paths are defined within a subvolume of instantaneous attribute data having the shape of a sphere or other solid figure. This is accomplished by extracting the subvolume of attribute data having a desired shape, defining multiple tomographic paths extending from point within the subvolume to its bounding surface, combining instantaneous attribute values encountered along each of the tomographic paths to determine multiple aggregate values, mapping the thus determined aggregate attribute values on the surface of the sphere using a color code, and displaying the color coded sphere. The attribute maps are correlated with preexisting geological or stratographic templates to identify features.</p> |
