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 stored on an allocation system, wherein each seismic input volume is a result of a different seismic survey comprising data recorded by a seismic recorder and received at a seismic input interface of the allocation system, wherein 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 representing chronostratigraphic layers;
(b) aligning, by the allocation system, the horizons of each seismic input volume to the horizons of the other seismic input volumes;
(c) performing a flattening operation, by the allocation system, for each seismic input volume to create a plurality of flattened seismic volumes;
(d) rendering, by the allocation system, each flattened seismic volume to create a stack of digital images representing at least a portion of the horizons in each flattened seismic volume;
(e) receiving an input, at the allocation system, the input aligning a first digital image from each flattened seismic volume, and, once aligned, using, by the allocation system, the first digital image from each flattened seismic volume to align a remaining set of digital images in 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.
