Introduction Geographic support for decision-making processes is based on various geographic products, usually in digital form, which come from various foundations and sources. Each product can be characterized by its quality [1, 2] or by its utility value for the given type of task or group of tasks, for which the product is used [3, 4]. In both cases, among others also positional and thematic accuracy are evaluated either as an exactly given value, for example, mean square position error, probable error, and so forth, or as a level of fulfilment of user¡¯s requirements expressed in percentage [5]. Decision-making processes are based on multicriteria decision-making, in which many factors are involved [6]. By a suitable combination of various factors, analytical products are created. They are the base for answering questions such as ¡°What happens if¡­?¡± That is the reason why various foundations are used for geographic support. They also usually have different characteristics and thus can very significantly influence the resulting analytical material. The aim of the paper is to contribute to the solution of the question of how it is possible to work with diverse spatial geographic information so that the user has an idea about the resulting product.
