Genetic algorithms represent an up-to-date method of process optimalization, where other solutions have failed or haven’t given any satisfactory results. One of these processes is automatic placement of map symbols in such a way so that no symbols should mutually overlay. A genetic algorithm solving this task including an exact formulation and a definition of the initial conditions has been described in this paper. The algorithm efficiency will be tested in diploma works in Institute of Geodesy, Faculty of Civil Engineering, Brno University of Technology.

The measuring in field is the most commonly used activity in various industrial branches. To be the results useful the data must be stored in a suitable database. There is a problem: to use either one of most of commercial database systems or to create the special purpose designed database? This question is discussed and an own approach of the database design is presented in this paper. The goal is the designed database with minimum of memory capacity occupied and the most rapidly information provided. It is supposed that the basic database design rules e.g. to avoid redundant data (normalization), ensure that the relationships among attributes are represented or facilitate the checking of updates for violation of database integrity constraints are respected. A special optimization method for common attributes reduction, for storing strings of variable length and for database reorganization is used.
