This is how a typical dispersion modeling result looks when shown as a map. ... Their numerical values are shown at the top. White normally means no data, but high values may be also shown as white if above the fixed high limit (that is, if no automatic normalization is used for colors). Note that calculations were done both for cell positions and for station positions, so both are colored. PO territories are filled by color corresponding to the average value of cells overlaying them. ...
