Computations of Bi-variable spatial relationships between the political divisions of Karnataka, India via Mahalanobis Distance

We show an application of Mahalanobis Distance to compute the degree of similarity between the bi-variables corresponding to two regions. The bi-variables considered include areas of each district and the areas of wetland regions within each district o f a Division-A and similar variables for each district of another Division-B. We considered four political divisions of state Karnataka that include 27 districts. Areal extent data for each district and the district-wise wetland regions are collated. Between every possible divisions, the Mahalanobis Distance is computed with respect to these two variables.
