1. A method of creating a mosaic from a plurality of different seismic surveys, the method comprising: (a) selecting a plurality of seismic input volumes, wherein each seismic input volume is a result of a different seismic survey and the seismic input volumes are representative of one or more subterranean regions of interest which are at least partially adjacent to one another, and wherein each seismic input volume comprises one or more horizons; (b) aligning the horizons of each seismic input volume to the horizons of the other seismic input volumes; (c) performing a flattening operation for each seismic input volume to create a plurality of flattened seismic input volumes; (d) rendering each flattened seismic volume to create a stack of digital images representing at least a portion of the horizons in each flattened seismic volume; and (e) aligning each stack of digital images representing each flattened seismic volume geographically on to a basemap; and (f) digitally compositing the stacks of digital images to create an animated mosaic of the plurality of seismic input volumes, the animated mosaic comprising an animated progression through the one or more horizons of all the seismic input volumes, wherein at least one of (a) through (f) is performed on a computer.
