    Opis:
    W artykule porównano zakres treści i formę graficzną trzech polskich cywilnych map topograficznych w skali 1:50 000: w układzie "1965", w układzie "1992" oraz w układzie "WGS-84".
    In Poland currently there are three topographic maps at the scale of 1:50 000 for civil use: -map in ,,1965" coordinate system published in 1977-1982 by the Head Office of Geodesy and Cartography, covering the whole country, - map in ,,1992" coordinate system, exept first 48 sheets of Mazowsze region, which were edited in ,,1942" coordinate system), published in 1995-2002 by the Surveyor General of Poland, covering almost 60% of the country's area, - ,,WGS-84" map in UTM projection published in 2003-2006 by the Surveyor General of Poland with the Polish Military Gegraphic Service, covering 25% of the country's area. Comparison of the range of contents and graphic form of the three maps clearly shows the superiority of the map in ,,1992" system. Compared to the other two it employs a new way of presenting built-up areas. It contains significantly more information about the function and intensity of exploitation of built-up areas and offers provides a more complete picture of anthropogenic landscape than any other map in that scale, in Poland or abroad. In addition, the ,,1992" map has the most detailed presentation of streets and relief. Detailed depiction of plant cover and crop areas is achieved by lowering the area limits, below which a particular object is not shown with its outline. Similarly, lowering of the length limit of watercourses and area limit of water pools led to a more detailed presentation of water network. The contents of the ,,1992" map was also enriched by a much larger number of acronyms and descriptions of public buildings and industrial sites. The map in ,,1965" system was printed in four colors, ,,WGS-84" map in five, and the ,,1992" map - in six. The comparison of graphic form of the three maps gave lowest marks to the least readable "1965" map. The ,,1992" map is characterized by wider use of color, which adds to its readability and attractiveness. Substituting black color, traditionally used for buildings and road network with brown resulted in higher graphic capacity and better presentation of public buildings and industrial sites. Consistent use of green for green areas, blue for water and light brown for relief facilitates perception of particular categories of map contents. Application of color patterns for grass areas and orchards allowed for a clear and detailed presentation of their outline. The graphic level of the .WGS-84" map is higher than that of former military maps and the map in "1965" system, partly due to the application of several solutions from the ,,1992" map (e.g. consistent use of green for green areas, simplified presentation of built--up areas). Some elements of the ,,WSG-84" map, such as main roads or borders of natural reserves, are more readable than in the other two. The comparison of the three maps in 1:50 000 shows that the newly planned map in this scale, which is to be prepared using the topographic database should base on the map in ,,1992" coordinate system.

    Opis:
    W artykule omówiono etapy opracowania koncepcji mapy topograficznej 1:50 000 wydanej w latach 1995-2002 przez GUGiK, a także podstawowe założenia tej koncepcji. Przy omówieniu treści i formy graficznej mapy zwrócono szczególną uwagę na nowy sposób ujęcia zabudowy.
    The first Polish topographic map in civilian version at the scale of 1:50 000 was prepared in "1965 system" by re-arranging and re-editing of the sheets of military 1:50 000 map in "1942 system". It was published in the years 1977-1982. In 1993 as a result of an order from the Surveyor General of Poland, preparation of a completely new concept of a topographic map in 1:50 000 was started. The first, initial instruction to this map was issued in 1995; its final version, which included the experience gathered during the editing of the first several dozen sheets appeared in 1998. The 1:50 000 map in its contents and graphic form refers to a map in 1:10 000, the preparation of which started in 1994. The new concept of a 1:50 000 map accounted for its multi-purpose character. An analysis of a range of contents and graphic forms in topographic maps of Western countries was conducted; the new concept also referred to Polish graphic tradition between the World Wars. Between 1995, when the publication started, and 2002, 589 sheets were published, which cover 60% of Poland's area. The forst 48 sheets of the Mazowsze region were edited in "1942 system", which bases on Krasowski elipsoid; all the following sheets were edited in "1992 system", basing on a GRS-80 ellipsoid.The map is printed on standard sheets of 580x470 mm. Every sheet includes the explanation of all the symbols and most abbreviations with Polish and English explications. On the new map the number of applied signs has been significantly reduced (in comparison to the previous map). At the same time its contents has been extended to include new, important elements, e.g. industrial and store areas, but stations, marked tourist routes, border checkpoints, bethymetry of lakes, border zones. However the biggest changes regarded methods of presentation of buildings. To show their variety a functional criterion has been applied. Industrial and governmental buildings have been differentiated from other buildings and built-up areas. Dwellings (including farm dwellings) have been differentiated according to their density and buildings' size. Compact multifamily dwellings, dense multifamily dwellings, dense single family dwellings have been shown as three different types of built-up area, while disperse dwellings have been marked with separate symbols for particular buildings or farms. The 1:50 000 map was printed in unified six color version (black, dark brown, blue, green, red, light brown). Application of dark brown to dwellings and roads was particularly important for the graphic picture, because it relieved the map and increased its graphic capacity, e.g. it made it possible to clearly mark government and industrial buildings. Consistent use of green for agriculture and vegetation and light brown for surface relief also improved the graphic quality of the map. In comparison to the previous map, the new 1:50 000 map has more precise drawing, which has been achieved with wider use of colors and patterns as well as the reduction of the size of symbols, their simplification, and reduction of line width. The map was met with positive reactions of its reviewers and users; its authors also got. The Awars of the Minister of Internal Affairs and Administration. After the reorganization of the Head Office of Geodesy and Cartography in the beginning of 2002, the publishing of further sheets was abandoned; it was decided, that the remaining area would be covered with a military map prepared in V Map Level 2 technology complying with NATO standards, and adapted for civilian use.

    Opis:
    W pierwszej części artykułu omówiono znaczenie generalizacji w procesie budowy Krajowego Systemu Informacji Geograficznej oraz teoretyczne zasady generalizacji sieci dróg i zabudowy dla skali 1:50 000. W drugiej części opisano narzędzia informatyczne do automatyzacji procesu generalizacji oraz implementacje bazy wiedzy dotyczącej reguł generalizacji w środowisku programowym DynaGEN. Poprawność opracowanej bazy wiedzy zweryfikowano przez przeprowadzenie dwóch eksperymentów. Pierwszy eksperyment dotyczył generalizacji warstw tematycznych Bazy Danych Topograficznych (BDT) sieci transportowej i zabudowy w obrębie podwar-szawskiej miejscowości Łomianki. Drugi eksperyment polegał na generalizacji warstwy tematycznej sieci transportowej w okolicach Kowalewa Pomorskiego.
    The most advanced software for generalization of digital data available on the market today is that by Laser Scan. The company participated in the AGENT The most advanced software project, which was described in the first part of the article. What resulted from the project was Clarity, a very advanced map generalization system. What differentiated Laser Scan from then contemporary software, was the fact that it accounted for the contextuality of generalization, i.e. the same objects can be generalized differently depending on the objects surrounding them. It was possible because of application of a unique object technology, where each object could be generalized in many ways depending on the context. The DynaGEN system by Intergraph is an alternative generalization software. It is less expensive and has significantly more practical applications. It uses the same generalization algorithms, but cannot do alternative operations. Therefore one can either generalize small areas in an interactive way, or generalize automatically with later manual corrections. Similarly to Laser Scan, it requires software configuration and also the construction of knowledge base. The second part of the article presents an implementation of the knowledge base containing the rules of generalization in DynaGEN environment. The accuracy of the arranged knowledge base had been verified by two experiments. The first one involved generalization of thematic levels of Topographic Database of the road network and buildings within the town of Łomianki near Warsaw. The second one consisted in generalization of the road network in the area of Kowalewo Pomorskie in Northern Poland. The knowledge base prepared in DynaGEN system contained two sets of rules. The first one included the rules applied automatically and which, in limited sequence, are used for the initial preparation of data. The second set contained the rules describing basic types of interactive generalization processes supervised by a cartographer, which were vital for the application sequence. The generalization of a road network consists of two stages. The first one involves an analysis and initial data processing. Its range includes a construction of a hierarchical model of a road network and the connection of road segments within the whole area. The second, main stage of the generalization of a road network involves selection and simplification of paved roads, dirt roads and paths. Generalization of built-up areas is performed in one step, without initial data processing. The prepared knowledge data describes the process of generalization of topographic data from 1:10000 into 1:50 000. It provides universal material which can be implemented in various software environments.

    Opis:
    W pierwszej części artykułu opisano i zilustrowano reguły generalizacji sieci drogowej i zabudowy przy opracowywaniu mapy topograficznej 1:50 000 na podstawie mapy 1: 10 000. W drugiej części artykułu zostanie zaprezentowana implementacja bazy wiedzy na podstawie zdefiniowanych reguł w środowisku programowym Dynagen oraz przykłady praktycznego wykorzystania tej implementacji do generalizacji Bazy Danych Topograficznych.
    Due to the development of geographic information systems, in the developed countries more than 70% of decisions in public administrations are taken basing on spatial data. Particular regions have their own databases with various levels of detail, usually corresponding to standard topographic scales (1:10 000, 1:25 000, 1:50 000 etc.). The question is whether it would be possible to keep just one, detailed topographic database and generate cartographic presentations in different scales from it, using automatic generalization of spatial data. This problem is particularly vital in Poland, because the National Geographic Information System (KSIG), which is being implemented at the moment, consists of, among other units, a Topographic Database (BDT) with the level of detail corresponding to the map in 1:10 000 and a Level 2 Vector Map (VMAP 2) with the level of detail corresponding to the scale of 1:50 000. Since 2002 the Faculty of Environmental Engineering and Geodesy of Agricultural University of Wroclaw together with the Warsaw University Chair of Cartography have been working on a research project "Automatization of the process of generalization of topographic maps from the scale of 1:10 000 into 1:50 000". In the first stage of the research attempts were made to elaborate a system of automatic genera-lization of road network and buildings with the use of DynaGen software. In the first part of the article the rules of generalization of these two components are presented and illustrated. Criteria and rules for the choice of streets and lower road categories are established (criteria of density, length, functionality and spatial relations). Generalization of buildings presented in the scale of 1:10 000 can be conducted in two ways: either with symbols of separate buildings or by replacing them with a symbol of a built-up area. In the first case we are dealing with the following types of generalizations: generalization of qualitative features, substitution of a collective symbol for separate symbols, choice of buildings, replacement of building outlines with symbols, building simplification, combining and changing of building location. In the second case separate objects (buildings) are replaced with a collective symbol (built-up area), the shape of which is further simplified, extended and combined.
