This multivariate geographic clustering technique has several advantages . Clustering is data-driven and empirical. This objectivity means that one obtains the same result every time, given the same data and a request for the same number of clusters. This is in contrast to regions drawn by expert opinion. Users control what data are included for consideration in the clustering process based on what is appropriate for their purposes.
Users are also able to select how many homogeneous regions are produced in the final clustered map.
Finally, any eclectic combination of continuous variables can be combined to form homogeneous areas on a map. Map clustering is a technique that invites the simultaneous geographic comparison of apples and oranges. Literature Cited Bailey, R.G. 1983. Delineation of ecosystem regions. Bailey, R.G. 1995.
