Rapid urbanization of countries, and forectasts predicting further development of urbanization as well as high material costs of this prcoess pose a requirement of more and more precise determination of plans and designing of development of modern cities. The data which are utilized in spatial planning of a city refer to small areas. The significance of land division into small areas is generally well known but thoro exitst, however, very diversifield ways of its presentation in practice. The practical solutions quoted by the author were employed in the FRG. The system of land division forms a certain kind of network construotion, which corresponds to the network of city streets. Particular elements of the city's area are divided into small blooks for which there has been constructed the following identificator providing a basis for information search: 0 - full area, 1 - planning area, 2 - housing district area, 3 - a part of municipal district, city, or other looation, 4 - district, 5 - a group of blocks of flats, 6 - block of flats, 7 - a side of a block of flats. In the discussed solution there are encoded in a geographical approach contours of blocks of flats since the collection of sides of a block of flats contains points of a polygon. Coding of contours of blocks of flats can be directly used as a model of borderlines image during automatic drawing of maps, on which can be placed numerical data reforring to a given area e.g. number of professionally active people, number of flats with a definite standard of facilities, shopping and service units etc. Both the scope and form of obtained information depend on the user of a system who provides appropriate data necessary for creation of branch bases while the above presented identificator. facilitates finding and proceesing of required information.
