Abstract :
This paper presents a method of how to produce a calculate and express spatial relations by a set of parameters. A new set of parameters more easily to understand and use is proposed based on two semantic meanings. Also the Voronoi diagram´s application in neighbor relations is discussed. By using the new set of metric parameters, complex spatial and topological relations can be easily expressed. And these relations can be stored together with the original data now.
