Software solution for proximities representation in GIS using adjacency matrix
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2013, Vol 6, Issue 1
Abstract
This paper presents how to design and implement a software module to achieve an alternative description of a map thematic compositions and applications of this representation. It starts from a layer containing spatial data of polygon type that can be described through adjacency matrix that holds neighborhood information for each of the existing vectors in the spatial feature. There are also presented applications of this representation: coloring maps with a minimum number of colors and the Moran index of spatial correlation calculation. The maps coloring is done thus for any two neighboring polygons they do not have the same color. The Moran spatial correlation coefficient is the standard used to determine the degree of dependence between the values of a variable in neighboring locations. It is used to identify a pattern in the spatial distribution of the valuesof an economic variables and the existence of common factors that influences the obtaining of these values.
