All things Being Equal….
The Concept of Distance Decay
Closer two objects are…..more likely to be interacting.
Therefore, the center of several objects, likely to be a common influence
Several ways to do this in the GIS
One is Kernel Density Analysis,Similar approach to theAnthrax example

3.142*10000 = 31420
Square kms = 1000*1000 = 1000000
1 / 31420 = 0.0000318
To express as square kms * by 1000000 = 31.83
3.142*10000 = 31420
Square kms = 1000*1000 = 1000000
1 / 31420 = 0.0000318
To express as square kms * by 1000000 = 31.83
