Description :
This article reports our efforts in developing a new pattern analysis method called the normalized mass moment of inertia (NMMI) that integrates both shape and nonspatial attributes into the analysis of compactness patterns. It first describes the theoretical model of the NMMI and its computation and then demonstrates its good performance through a series of experiments. It further discusses potentially broad applications of this approach in the contexts of urban expansion and political districting in Wisconsin. In the political districting context, higher NMMI of a congressional district suggests a lower degree of gerrymander and vice versa.
