[Meng, 2003]. Generalization entails a number of different rules that must be correctly
applied in a certain sequence. Different roles have different rules and different knowledge
base. This compilation of a dynamic system is a possible solution to the automatic
generalization. In the context of digital cartography and expert systems is therefore very
necessary to examine and interpret the processes at manual generalization. The overwriting
the procedure of the cartographer into a sequence of a procedure of very well defined
processes is a key objective in creating a successful expert system [Lee, 1994].
Implementation of the knowledge of experts to the programs for work with a map can
greatly specify and simplify the whole process. Automatic generalization is interesting
example. These intelligent guides can be found in different software such as ArcGIS,
DynaGen and LaserScan. The development of intelligent systems is a major commercial
application of artificial intelligence (AI) which is proposed to increase the quality and
availability of knowledge for automated decision-making [Boss, 1991].
For common users it is much more preferable to use freely available software resources.
These resources can help with the creation of maps. In the following text, there are some of
these applications. The "MapBrewer" system is named after the researcher and cartographer
Cynthia Brewer. It is a new type of a system developed to encourage the creation of maps. It
helps the user always with only one particular aspect in the production of maps.

Three versions, namely ColourBrewer [Harrower, Brewer, 2003] instrument for the correct
choice of colour composition, SymbolBrewer [Schnabel, 2005] for the selection of
appropriate map symbols, and TypeBrewer [Sheesley, 2006] to the appropriate font, are now
available. These described systems can be rather referred as "digital teaching assistants".
