Tool Ordered Weighted Averaging
The ordered weighted averaging (OWA) tool calculates for each cell the weighted average from the values of the supplied grids. The weighting factor for each grid value is defined with the 'Weights' table. If the 'Ordered' flag is unchecked, the order of the weights correspond to the order of the grids in the input list. If the 'Ordered' flag is checked, the grid values will be sorted and the weights will be assigned to the values in their ascending order, i.e. from the lowest to the highest value.
