This paper contributes to the field of physical network interconnection decision support. This type of problems are very complex to solve for two main reasons: The computational complexity is high due to its combinatorial nature and to the calculation of parameters to evaluate the solutions. Usually, these parameters are related to the deployment investment, or performance and reliability. Geographical and statistical factors are used for their calculation and are normally considered as constant regardless of the specific deployment place. The main contribution of this work is to consider these factors as variable, and to evaluate their effect. A case study is presented and vectorized maps and image processing is used in order to provide the proper scenario for the evaluation. The objective can be defined as a simple question: Is the interconnection decision different when these factors are constant or variable?
