A comparison of optimal classification strategies for choroplethic displays of spatially aggregated data
Robert G. Cromley · International Journal of Geographical Information Systems · 1996
A debate has ensued from the question of whether the attribute values of spatially aggregated data need to be classified prior to the display operator for representation as a choropleth map. Some recent studies have concluded that choropleth maps using Jenk's optimal classification scheme are more easily interpretated than either unclassed maps or more traditional classification methods. This paper presents a range of optimal classification strategies for displaying spatially aggregated data including techniques designed to enhance value identification.
