Abstract: This paper illustrates the usefulness of cartographic and centrographic methods in examining the locational characteristics of health care resources, such as specialist physicians' offices. Cartographic analysis involving map comparisons not only describes the nature of particular spatial patterns, but it also suggests relevant hypotheses on the basis of observed locational relationships among the mapped phenomena. Centrographic analysis generally substantiates the findings of simple map analysis by providing certain objective quantitative measures regarding the basic characteristics of a point distribution; additionally, it generates a graphic summary, the Standard Deviational Ellipse (SDE), which offers a convenient means for direct comparison of multiple spatial patterns. The essentially complementary nature of the two methods is highlighted, and it is concluded that they are most useful when used in conjunction with one another.
