<element name="DESCRIPTION" text="This algorithm calculates the kappa index of agreement for 2 raster layers. This index can be used to check the degree of similarity between two layers such as two land use layers corresponding to two different dates. The Kappa index is not biased by random coincidences, since it takes into account agreement that could occur by change (expected agreement). Kappa index values range from -1 to 1. 1 indicates a complete similarity, while the -1 defines a negative sign correlation. Values around 0 indicates that there is no correlación between the layers. Values higher than 0.75 indicate a very good correlation. " description="Description" type="0"> |
