Users may want to set goals for a municipal area, such as "each district should have one square kilometer of open space". Those thresholds can be used to visualize data, such as controlling color breakpoints for choropleth maps. In the previous example, districts with >= one square kilometer of open space would be green, while other districts would be shaded proportionally to their values.
