decision rule:� The criterion used to assign cells to a prototype feature in TNTmips feature mapping.� Cells in the image are tested against the decision rule, and those that match are highlighted as prototypes.� You select the desired decision rule when setting up the raster objects to be analyzed by feature mapping.� A simple decision rule would be to compare the three color values of each cell on the display to three color values known to occur in the target feature.
