		<element name="DESCRIPTION" text="This algorithm quantifies the aggregation of similar values in a raster layer, using the index defined by Hong et al., 1991.&#10;&#10;Here is an example: The following figure shows two tables that represent two small raster layers. Both contain the same values, with the same average and standard deviation. However, the cells with similar values are grouped on the first layer while on the second one they are scattered. The aggregation index measures the degree of grouping." description="Description" type="0">
