This paper presents a new methodology for hierarchical spatial clustering of contiguous polygons, based on a geographic coordinate system. The proposed algorithm is built upon a modification of traditional hierarchical clustering algorithm, commonly used in the multivariate analysis literature....

This paper studies a methodology for hierarchical spatial clustering of contiguous and homogeneous polygons, based on a set of binary variables. The proposed algorithm is built upon a modification of traditional agglomerative hierarchical clustering algorithm, commonly used in the multivariate...

The mapping of frequency rates of events is an important tool for guiding public policy. Nevertheless, this problem has not received adequate attention by most researchers. In many studies, the used ratios have serious problems when the geographic units have a small population at risk and when...

In Brazil, the regional development policy is directed by the regional development funds for the Northeast (FNE), the North (FNO), and the Central-West (FCO), which invested more than ?36 billion in lagging regions between 2004 and 2010. This policy seeks to facilitate the economic and social...

This study aims to present a model for economic evaluation of the expansion of the broadband network for the Brazilian municipalities. This is done taking into account not only the economic return, but also the cost of expanding the network. Return is calculated from three criteria of...
