ABSTRACT
Spatial units are an important carrier of numerical data on tested statistical characteristics of selected social-economic phenomena. They are in the relation of contiguity to one another, which can be expressed by the binary matrix of contiguity. Its 1-elements indicate occurrence of common boundary, and zeros – no boundary. In the work various divisions of spatial units have been presented as well as their properties and description of contiguity allowing determination of the contiguity matrix. It stands out with many analytical properties. Its illustration has been shown on land districts of Podkarpackie Province.
KEYWORDS
