An approach to measuring urban sprawl by proximity, and housing unit and population density.
The Metropolitan Sprawl Gradient (MSG) approach tested in the Lexington-Fayette County region of Kentucky measures sprawl by combining measure of proximity with housing unit and population density. Urban sprawl has been characterized by the proximity to a variety of public use facilities such as the post office, supermarket, library, etc., as well as the density of people and/or housing units. This project uses proximity and relative densities to help visualize an urban development surface. The proximity to public services is determined using ESRI's ArcGIS tool, Euclidean Distance, from point, line (bus route), or polygon (parks) features representing those services. The study utilized publicly available data from the Kentucky Geography Network, along with data created using heads-up digitizing in conjunction with Google Maps and Local Live Maps to geolocate places of interest.
