1. A computer-implemented method executed by one or more processors, the method comprising: identifying a master model associated with a spatial region, the master model including a plurality of pixels, each pixel corresponding to a particular portion of the spatial region and including a length and a width for the particular portion of the spatial region; identifying a data set including values of a physical property of at least a portion of the spatial region for a particular time; determining, based at least in part on the data set, a set of values of the physical property including a value for each pixel in the master model; and storing the set of values of the physical property as a value for each pixel.
