The various Grid Overlays in the Tygron Platform, both for specific calculation models as well as for managing and displaying data, can calculate very acurate and location-specific results. There are a number of use-cases in which it is desirable to average the results out over a larger area, or otherwise introduce a spatial buffering of the results. In these cases, an Average Overlay can be set up to take a different Grid Overlay as its input, and apply a spatial effect for each location based on surrounding cells. The most common direct use-case is the creation of heat maps, where seemingly overly-accurate results are averaged out over an area to give a more general impression over a broader region.
