Spatially Lagged Choropleth Display

Abstract

Choropleth display of spatial information is a fundamental feature of mapping and geographic information system technologies. There has long been a desire to impart some spatial influence in the class selection and delineation process of choropleth display. This paper presents an approach for representing the spatial influence of neighboring areas in the creation of choropleth classes. The usefulness of this approach is explored using suburb level crime statistics for Brisbane, Australia.
