The most typical application of the generalization tools is to clean up a classified image derived from a satellite or a scanned map. The second general use of the tools is for reducing the detail in a dataset that is not relevant to the ensuing analysis.
Below is a classified image derived from a satellite. Notice that there are many isolated small zones of data that are either misclassified or irrelevant to the analysis.
Using the generalization tools, the following image was produced and is the final land use map that will be used in further analysis. For a complete understanding of how the tools were used to create the final map, see Understanding generalization analysis.
